Expert Coin Grading
Know not your coin's identity, but also its condition. Our Sheldon scale grading engine can assign a grade to your coin from Poor (P-1) to Gem Uncirculated (MS-65). Each grade has a breakdown of surface quality, strike, and luster. See how a coin's grade affects value before you buy or sell or add them to your collection.
Rare & Error Coin Detection
Believe you can detect a special coin? The Coin ID system flags rare variants, error coins, or variants that people commonly overlook that end up being worth a considerable amount. Each scan adds a rarity and grade breakdown as well.
Smart Collection Valuation
The app allows users to track their coin collection. Coins can be organized by country or value. The app also monitors your collection's total worth as market prices update in real time.
