Auctori

Auctori identifies US colonial copper coins to the die variety from two photos, one of each side. Every colonial copper was struck by a pair of hand-cut dies. Auctori reads both and names the pair by its standard reference number: Maris for New Jersey, Miller for Connecticut, Ryder-Richardson for Vermont, Ryder for Massachusetts, Vlack for Machin's Mills and Newman for Fugio. For each coin you get: - The die variety, with how closely each side matched - Where the photo matched known coins, and what to look at when two varieties are close - A grade range - Recent auction results for that variety, with grade, date and auction house Scan with the camera, or upload photos you already have. Keep your coins in a collection, value each one from the sales you pick, and share a coin or the whole collection with a link. Supported now: New Jersey coppers, Connecticut coppers, Vermont coppers, Massachusetts cents and half cents, Machin's Mills halfpence, Fugio cents and Nova Constellatio coppers.
