Wide Database — One scan — 99% Accuracy.

Know Your Coin Worth with a Scan!
The app acts as a coin scanner to read both sides of any coin — worn, ancient, or foreign and returns the full identity in seconds that stump even seasoned numismatists.
Every identified coin comes with:
• Full coin history, origin details, and mintage data
• Mint count and production year
• Current and historical market value with instant appraisal
• Grading insights from numismatic experts
• Collector demand and scarcity rating

Expert Coin Grading
Know not just 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, sell, or add it to your collection.
Rare & Error Coin Detection
Believe you can detect a special coin? The Coin ID system flags rare variants, error coins, or mintmark anomalies 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 & Catalog
The app allows users to catalog their coin collection. Coins can be organized by country or value. The app also monitors your collection's total worth and appraisal estimate as market prices update in real time.
