Question 1

How does Coin Error Expert identify coin errors and varieties?

Accepted Answer

Coin Error Expert uses a specialized RAG (Retrieval-Augmented Generation) AI vision system ground-truthed against premier numismatic reference catalogs including Variety Vista, Error Ref, and the Cherrypickers' Guide to accurately distinguish true mint errors (like Doubled Dies, Repunched Mintmarks, and Off-Center Strikes) from common strike doubling or machine damage.

Question 2

Can Coin Error Expert scan paper money and fancy serial numbers?

Accepted Answer

Yes. Coin Error Expert includes a dedicated Paper Money & Banknote AI engine that detects fancy serial numbers (Radars, Super Radars, Repeaters, Ladders, Star Notes, Binaries, Trinaries, Birthday Notes) and Bureau of Engraving and Printing (BEP) manufacturing errors like cutting errors, gutter folds, and ink anomalies.

Question 3

How does the 2x–10x Digital Loupe work?

Accepted Answer

The 2x–10x Digital Loupe is a browser-based magnification tool that allows collectors, marketplace buyers, and auction intake specialists to inspect ultra-high-resolution die diagnostics and verify AI scan findings directly on any device without downloading external software.

Question 4

Can I prepare coins for PCGS, NGC, PMG, or auction house submissions?
