Coin Identifier: Grade & Value

Name any coin in seconds — then get estimated grade, value-by-grade, mint-error check, and live melt prices. Three free scans to start.

Coin Identifier turns your camera into a pocket numismatist. Photograph a coin's front and back — US or world, modern or ancient — and get an expert-style breakdown in seconds: what it is, what grade it's likely in, and what it's worth.

MINT ERROR CHECK ON EVERY SCAN Every coin is examined for the things collectors actually hunt: possible doubled dies, off-center strikes, repunched mint marks, and die cracks. Findings are flagged as possibilities worth investigating, never as confirmed varieties.

WHAT ONE SCAN TELLS YOU • Full ID — name, country, year, denomination, mint mark, and series • Composition & specs — metal, fineness, weight, diameter, and mintage • Estimated grade with a value-by-grade price ladder, so you see the worth at every condition • Estimated value range — an AI-derived market estimate, never a fake-precise single number • Melt value — precious-metal worth for silver, gold, platinum, and palladium coins, at reference spot prices • History, interesting facts, and handling tips (rule #1: never clean a coin)

BOTH SIDES, PLUS THE MINT MARK Shoot the obverse, then add the reverse and a close-up of the date or mint-mark area. Two sides beat one: it is what separates near-identical issues, and the close-up is what lets a read reach its highest confidence tier.

BUILD YOUR COLLECTION Every identification you keep saves to a private, on-device collection. See your total collection value, follow set completion for series like Wheat Cents and State Quarters, and export the whole collection to CSV for your own spreadsheet.

POCKET GUIDE — WORKS OFFLINE Collecting eras, series, mint errors, and grading guides are bundled inside the app. No signal needed at the flea market, the estate sale, or the coin show.
