Identify your coin, understand its errors, prepare it for grading, and get it ready to sell all in one place.
Upload a photo of any US coin and our AI identifies the error type — DDO, DDR, Wrong Planchet, Die Cap, Brockage, and 20+ more — in seconds. It distinguishes true mint errors from machine doubling.
Every scanned coin is stored with full numismatic fields: denomination, mint mark, die variety, variety class, Wexler reference, estimated grade, and photos.
Buy and sell error coins directly with other collectors. Listings include AI-verified error type, grade assessment, and attribution data.
Generate a professional consignment packet for Heritage Auctions, Stack's Bowers, or GreatCollections — complete with error classification, variety reference, condition notes, and AI analysis.
