CoinAppraisalApp tests coin appraisal apps for estate executors, insurance filers, and pre-sale collectors who need to know whether an app estimate is accurate enough for their situation — or whether they need a certified appraiser. We draw the line clearly.
Who We Are
This team started after one of us spent three months appraising a deceased parent's coin collection for probate. The inherited coins were scattered across two safes and a safe-deposit box — roughly $80K across mixed circulated US coins, a few key dates, and unexpectedly, a small Canadian silver hoard. We used four different apps to value them, got four different answers, and then hired a certified appraiser for the court filing. The appraiser's number was sobering: we had underestimated by 18% using apps alone. The experience taught us which apps helped and which misled. We decided to test coin appraisal apps the way an executor or insurance adjuster actually uses them — not as a hobby, but as a decision tool for real money.
Our editorial lens is simple: an app appraisal is not a replacement for a certified appraiser in every case. But it is often good enough to answer the question 'should I sell, keep, or grade this coin?' For estate valuations over $25K, IRS donations, or contested probate, a human appraiser is required by law or prudence. For casual collections, insurance claims under $5K, or quick pre-sale estimates, a solid app is a time-saver and a real tool. We review apps and online appraisal services by drawing that line honestly.
Methodology
We test coin appraisal apps against a fixed portfolio of 31 coins — a mix designed to replicate an estate or inherited collection, not a specialized numismatic collection. Our test set includes Lincoln wheat cents (1909-1958), Mercury dimes (1916-1945), Washington quarters (1932-1964), Morgan dollars (1878-1904), Canadian silver dollars (1920-1966), US nickels (Jefferson and Buffalo), and Indian Head cents. We range across circulated grades, minor damage, and a few key dates to see how each app handles grade sensitivity and damaged-coin adjustments. Total test time: approximately 85 hours per app over three months, including repeat testing after app updates and price-feed changes.
We evaluate each app on five criteria: (1) accuracy of the per-coin valuation against recent eBay SOLD and PCGS CoinFacts data; (2) clarity about grading sensitivity — does the app show price ranges across grades, or does it lock onto one estimate?; (3) grading-economics insight — does the app calculate whether it makes financial sense to send a coin for professional grading?; (4) handling of damage and cleaning caveats — does the app reduce value for cleaned coins, or does it silently overestimate?; (5) Canadian coin coverage — does the app treat Canadian silver dollars with the same pricing depth as US coins, or are they sidelined? We re-test each app quarterly and after any major pricing update.
Our Standards
We score apps on whether they help you decide whether to spend $60–$200 on professional grading. Most appraisal apps show a single dollar value per coin — useful for insurance, useless for deciding if grading is worth the cost. A strong appraisal app shows a price range across grades and calculates the grading ROI: if your Lincoln cent is worth $8 in VF-25 but $22 in MS-63, and grading costs $20, the math is simple. If the app hides this calculation, or shows only one price, you have no way to know whether grading is worth the gamble. We also test Canadian coin valuation with equal rigor. Canadian silver dollars, in particular, are graded and priced differently than US coins — some apps reduce Canadian coin values by 30–40% simply because they lack native pricing data. An honest app tells you when it is uncertain about a Canadian coin's authenticity or grade — not silently undervaluing it. We mark down any app that treats Canada as an afterthought when the user's collection might be 20% Canadian.
Disclosure
We do not accept paid placement or partnerships with app developers; we do not review any app we have not used for at least two weeks of real testing against our 31-coin portfolio. We do not calculate per-coin grading ROI for you — we only test whether the app does; many users need a certified appraiser for estate, tax, or legal purposes, and we state that clearly and often. We do not claim expertise in world coins, ancient coins, or specialized numismatic varieties beyond our test set; we test apps on the coins most users actually inherit or insure — circulated US and Canadian coins from the 20th century.
