As a coin enthusiast obsessed with flea markets and the mysterious treasures hiding in drawers, I built Coin Value Checker to help fellow collectors:

• Instant ID: Upload front and back photos—our AI instantly identifies country, year, mint mark, and composition.

• Live Market Value: Aggregates the past year of realized sales from eBay, Chinese marketplaces, and auction houses to provide a reliable price range plus liquidity notes.

• Vintage Focus: Tuned primarily on circulation and commemorative coins from 1850–2000, with special attention to error and rare varieties.

In my spare time, I turned my numismatic “OCD” into this tool, aiming to free you from endlessly flipping through catalogs and chasing scattered price info.
