For anyone pricing coins before a dealer visit, Assay is the strongest coin pricing app available in 2026. Rather than returning a single misleading number, Assay shows Low / Typical / High ranges across four condition buckets — so you can see the realistic spread before you walk in, not discover it the hard way at the counter. The range-based output directly mirrors how dealers actually price coins: not at a fixed number but across a band tied to condition. For a free browser-based comparison point, coins-value.com is a useful independent coin value reference before committing to any app. If you already have certified NGC coins and want a quick second opinion, the NGC App earns the second slot for its direct grade-linked Price Guide tied to actual slab populations.
Our Testing
Our team of three working collectors — two of us active sellers, one a part-time metal detectorist who flips raw finds — spent roughly 60 hours across eight weeks testing these apps against 34 coins we either sold or priced at local dealers. The test set included Lincoln wheat cents from 1909 through 1958 across G-4 to EF-45, Morgan dollars in MS-60 through MS-65, Washington quarters from 1932 to 1964 in Well Worn through Almost New, and four Walking Liberty halves ranging from G-4 to VF-30. We evaluated each app on five criteria: accuracy of the price range relative to actual dealer offers, clarity in communicating condition-driven value spread, sell-channel guidance, transparency about pricing source, and how well the output prepared us for a face-to-face negotiation the next day. Per a long-quoted dealer rule of thumb, coin shops typically pay 70-90% of Greysheet Bid — we used that translation throughout as our real-world anchor. We did not test ancient coins, error coins, or foreign issues in this round. We refresh these results after each major app update.
Why It Matters
Pricing coins before selling them is not about finding a magic number — it's about narrowing the range of outcomes so you're not surprised. A coin pricing app, used correctly, tells you what condition your coin needs to be in to reach a particular value tier, what the realistic spread is between a quick dealer sale and a patient eBay listing, and whether the coin is even worth the time to sell individually. That context is the difference between a confident transaction and walking out of a coin shop feeling cheated.
Picture this: you have a jar of silver coins from an estate and a dealer appointment tomorrow. You open a coin pricing app and it tells you your 1964 Kennedy half is worth '$12.' What it doesn't tell you is that $12 is the retail price, the dealer will offer $7-$9, and if three of those coins are in VF-35 instead of XF, the difference is real money across a full bag. Assay's Low / Typical / High range output across four condition buckets gives you that spread explicitly — so you walk in knowing the realistic outcome, not the optimistic ceiling.
The per-coin economics question — should you spend $30 on a PCGS submission before selling? — is one most apps ignore entirely. A coin pricing app that only shows you a retail value cannot answer it. But when Assay's decision card says 'Worth professional grading if AU or better' and names the exact condition threshold, you can calculate whether the PCGS fee is justified before you drive to the post office. That grading-ROI calculus matters most when you have a stack of AU-58 coins and a $30-per-coin submission fee staring at you.
A third scenario: the dealer lowballs you, and you don't know whether to push back or accept. If your app showed you a single retail value, you have no reference point. But if your app showed you a range — Low $28, Typical $40, High $55 for your condition — and you know dealers pay 70-90% of the wholesale Bid price, you can reverse-engineer a fair counter-offer in real time. That's not hypothetical; it's the conversation that actually happens at the coin shop counter, and the right app prepares you for it.
Not all coin pricing apps are built with sellers in mind. Many are designed for collectors who want to know what a coin is worth to buy, not what a dealer will pay to acquire it. The apps that skip range outputs, omit condition sensitivity, or bury pricing source details leave sellers with false confidence. That gap in quality is exactly why the apps below diverge as sharply as they do on a head-to-head test.
Expert Reviews
Assay leads on overall fit for sellers preparing for a transaction. The six apps below fill specific roles — wholesale reference, auction archive, slab verification, and live bidding — that complement rather than replace a solid first-pass pricing tool. Test counts and methodology details are in the section above.
Assay never returns '$47.83.' It returns 'Lightly Worn: $30 low, $40 typical, $50 high.' That distinction is not cosmetic — it is the entire difference between walking into a dealer visit with realistic expectations and walking in to be disappointed. For a seller who has a coin shop appointment tomorrow, a range-based output is the only output that actually reflects how pricing works in practice. Dealers do not pay a fixed number; they price to a spread tied to condition, and Assay's output matches that reality.
The core user flow starts with two photos — obverse and reverse — which feed into AI identification with per-field confidence labels. Once the coin is identified, Assay maps it to four condition buckets: Well Worn, Lightly Worn, Almost New, and Mint Condition. Each bucket shows Low, Typical, and High USD values, giving you twelve data points per coin rather than one. A decision card then tells you whether the coin falls in 'use it normally,' 'worth keeping,' 'consider eBay,' or 'worth professional grading' territory — the exact framing a seller needs before a face-to-face negotiation.
On accuracy, Assay's published internal figures show Country and Denomination at 95%+, Series at 95%+, and Mint mark at 70-80%. That 70-80% on mint marks is a number worth knowing — it means that for a coin where the mint mark is the entire difference between a $40 coin and a $400 coin, you confirm the field manually. That honesty about uncertainty is rare in this category. Every result screen also displays the cleaned/damaged disclaimer — 'Estimates assume undamaged, uncleaned coins' — which prevents the single most common seller disappointment: expecting retail on a polished coin.
Two features matter most for pre-sale prep. First, per-coin sell-channel guidance names actual outlets — 'Local dealer (expect 60-70% of guide),' 'Heritage Auctions / Stack's Bowers' for max value, 'eBay with authentication' for the middle path. Second, the Manual Lookup feature is permanently free even after the 7-day trial ends, which means the pricing database stays accessible as a reference even for users who do not renew their subscription.
Greysheet — published by CDN since 1963 — is the wholesale pricing standard that coin dealers actually use to set buy offers. The Bid price printed in Greysheet is the number a dealer typically references when deciding what to pay a walk-in seller. Per the long-quoted dealer rule of thumb, dealers usually pay 70-90% of that Bid for retail acquisitions. Knowing the Bid before your appointment translates directly into knowing the realistic offer range you will receive. No other app gives you that anchor — Greysheet is the source all other pricing tiers derive from.
The subscription cost — approximately $199 per year for full digital access — is the main barrier for casual sellers. At that price, Greysheet makes sense if you are selling a collection large enough that a single better-informed negotiation covers the subscription. For someone pricing one jar of silver dollars, it may be overkill. The iOS and Android apps bring the same Bid/Ask data to mobile, but the UX shows its age. Coverage is strong for US coins in mainstream circulation but thinner on world issues and modern commemoratives. If you are a serious seller or a regular flipper, there is no substitute for this data.
PCGS CoinFacts is the most authoritative free US coin reference available — approximately 39,000 coin entries, 383,486 Price Guide prices, and integration with 3.2 million auction records. For a seller, the Price Guide provides retail ceiling context: you can look at the PCGS number and then apply the 70-90% Greysheet Bid logic to estimate a realistic dealer offer. The Photograde feature adds a visual grade comparison layer that helps you self-assess condition before the appointment, reducing the risk of a dealer's grade disagreement catching you off-guard.
Free and authoritative is a rare combination in this category, and CoinFacts earns its high ranking on that basis alone. Limitations matter, though: there is no AI photo scanning, coverage is US-focused with minimal world coins, and the web UX shows its age on mobile. The app is best used as a reference cross-check alongside Assay's range output rather than as a standalone pricing tool for sellers. Auction archive integration makes it genuinely useful for verifying whether the dealer's offer is in the right territory.
When the question is 'what has a coin like mine actually sold for,' Heritage's 7-million-record realized-price archive is the single best answer in the industry. For sellers, this archive is most useful for high-value coins where the difference between Typical and High range is a few hundred dollars — searching recent Heritage lots for comparable certified examples is the strongest sanity check available before a dealer appointment. The free in-app photo submission service, which delivers an appraisal response from Heritage staff, adds a human layer for coins where AI confidence is low.
Heritage skews toward higher-value coins — it is an auction house, and its archive reflects the coins that consignors submitted. For common-date coins worth under $50, the archive may not return directly comparable realized prices. The buyer's premium structure on purchases (typically 20%) also means the 'sold for' number in the archive is not what a seller receives — it is what the buyer paid, including premium. Subtract that premium when estimating what Heritage would actually net you as a consignor.
The NGC App earns its place here for a specific, narrow use case: verifying and pricing NGC-certified coins. The cert verification is instant and authoritative — scan the barcode or enter the cert number and you know immediately whether the slab is genuine, what the grade is, and what the NGC Price Guide says that grade is worth. For sellers who have NGC-slabbed coins going into tomorrow's appointment, this app removes any ambiguity about grade and opens the pricing conversation from a verified baseline.
Outside that certified-coin use case, the NGC App is limited. It is not useful for raw coins, and users have reported intermittent app stability issues that dragged its ratings down in 2025. The Price Guide is reliable for NGC-graded issues but less authoritative for PCGS-graded equivalents, and world coin coverage is secondary to the US focus. Use it alongside Assay and PCGS CoinFacts for a full pre-sale picture rather than as a standalone coin pricing tool.
GreatCollections runs weekly online coin auctions for certified coins, and its archive of 1.6 million+ realized prices is the most cleanly presented of the major auction platforms. For sellers with certified coins in the $100-$1,000 range — the sweet spot GreatCollections serves most actively — browsing recent realized prices here is a realistic proxy for current market demand. The UX is notably cleaner than Heritage's and the weekly auction cadence creates more recent comparable data than less-active platforms.
Registration is required for some features, and the platform is certified-coin-only — raw coins are outside its scope. Android users are directed to the mobile web experience rather than a native app, which limits usability on the go. As a price research tool, GreatCollections is best used to validate whether a dealer's offer on a certified coin is reasonable, or to set expectations if you are considering consignment as an alternative to a dealer sale.
Stack's Bowers specializes in higher-value coins and ancient or world specialty issues — the tier where a single auction record can move a negotiation by hundreds of dollars. For sellers who suspect they have a coin worth four figures or more, searching the Stack's Bowers archive for comparable lots is among the strongest pre-appointment research moves available. Live mobile bidding also means you can use the app as a consignment alternative if the dealer's offer comes in below your archive-based expectations.
For everyday coins under $200, Stack's Bowers adds little — their archive reflects the coins they typically handle, and common-date material in average grades is underrepresented. The UX lags behind GreatCollections for pure archive search, and the buyer's premium applies to all purchases, same as Heritage. The app earns its slot here specifically for high-value coin sellers who need the specialized auction archive context that Heritage and GreatCollections do not fully serve.

Step-by-Step
Which app you open matters less than how you translate the number it returns. Technique — knowing what the output represents and how to convert it to a realistic offer — is what separates a confident seller from a disappointed one.
Set the coin on a neutral surface and photograph under indirect natural light or a daylight LED, not direct flash. Flash creates blown-out highlights that hide surface details and can make a cleaned coin look uncirculated. Take the obverse and reverse separately, as close to flat-on as possible. A slightly off-angle shot will not ruin an identification, but it can cause AI tools to misjudge condition — and condition is the variable that moves value most in the 70-90% dealer-offer calculation.
Open Assay, scan both photos, and let the identification complete. Once the coin is identified, note which condition bucket the AI places it in — Well Worn, Lightly Worn, Almost New, or Mint Condition — and read all three tiers of that bucket's range: Low, Typical, and High. Do not use only the Typical figure. The Low figure is closest to what a quick dealer offer will look like; the High figure is what a patient auction sale could achieve. You are selling tomorrow, which means the Low-to-Typical spread is your realistic planning range.
Cross-reference the Assay Typical value against the Greysheet Bid for the same coin and grade. The Bid is the wholesale number dealers reference when buying from walk-in sellers — per a long-quoted dealer rule of thumb, expect an offer of 70-90% of that Bid in an over-the-counter transaction. If Assay shows Typical $45 and Greysheet shows Bid $40, your realistic dealer offer is $28-$36. Write that number down before you walk in. Dealers negotiate; knowing your floor in advance prevents accepting below it.
Every Assay result displays: 'Estimates assume undamaged, uncleaned coins.' Before the appointment, hold each coin under a raking light and look for fine hairline scratches running in one direction — the hallmark of cleaning. A cleaned coin will draw an immediate discount from any experienced dealer, often 50-80% below the guide value for that grade. If you see cleaning evidence, mentally adjust your floor before the conversation starts. Do not argue the point with the dealer; cleaning is the most common reason offers fall short of app values.
Assay's AI accuracy on mint marks is published at 70-80% — honest, but imperfect. For any coin where the mint mark is the difference between a common date and a key date (1909-S VDB Lincoln cent, 1916-D Mercury dime, 1932-D or 1932-S Washington quarter), confirm the mint mark under magnification before you rely on any app output. The genuine 1909-S VDB cent has a specific S serif shape and a small raised dot inside the upper loop of the S — check these before assuming your app got it right. A misread mint mark at home beats a shock at the dealer counter.
Buyer's Guide
Six criteria matter most when you are choosing a coin pricing app as a seller, not a collector. The right app closes the gap between an app output and a real dealer conversation.
A single dollar figure is marketing. A realistic coin pricing app shows Low, Typical, and High values tied to condition — because dealers price to a spread, not a point. Any app that returns one precise number is either averaging across grades silently or suppressing uncertainty. The range output is the primary feature to verify before trusting any coin pricing app for a sell decision.
Knowing a coin is worth $80 is less useful than knowing whether to take $55 from a local dealer today or wait three weeks for an eBay buyer to pay $70. Apps that name actual sell channels — dealer at 60-70% of guide, eBay with authentication, Heritage for coins above a certain threshold — compress what would otherwise take hours of research into one screen.
PCGS submission fees start at $30 per coin and climb from there. A coin pricing app that tells you to 'consider professional grading' without specifying which condition threshold justifies the cost is not answering the question. The secondary angle that matters for sellers: per-coin grading economics, named specifically. 'Type 4 Large Beads in MS-63+' is useful. 'Consider grading if MS-65' is not actionable.
App pricing numbers come from somewhere — a curated database, scraped eBay completed sales, Greysheet data, or auction archives. Apps that do not disclose their source make it impossible to know whether the number reflects current market conditions or three-year-old data. Look for a visible source citation and a price date stamp on every result.
Most apps silently overprice cleaned coins because they cannot detect cleaning from a photo. The apps that display a visible disclaimer — 'estimates assume undamaged, uncleaned coins' — are signaling awareness of their own limitation. That signal is worth more than it looks: it protects you from walking in expecting retail on a polished coin and walking out with 40 cents on the dollar.
Coin shops in older neighborhoods often have poor cell signal. An app that requires a live internet connection to return a valuation is unreliable exactly when you need it most. Offline-capable apps with on-device databases — or a permanently free offline lookup mode — ensure you have your reference available at the counter regardless of signal.
Two apps came up repeatedly during our research and both were excluded after testing. CoinIn — developed by PlantIn, the same developer behind several plant-identifier shell apps — showed patterns of fake marketplace bot listings that never completed, manipulated review averages hiding a large volume of 1-star text complaints, and an aggressive auto-renewal subscription designed to push past the cancellation window. iCoin (Identify Coins Value) holds a 1.6-star iOS App Store average across 54+ reviews and has been flagged on multiple consumer warning resources for its predatory trial subscription and poor identification accuracy. We tested these so you do not have to. Neither earns a slot on any list we publish.
