Detect the Counterfeit
Real counterfeit cases from the ANA Reading Room and CoinWeek. Each playthrough draws eight random rounds — two coins, four clues. Can you spot the fake?
Inspect Both Coins
Each round shows two coin photos — one genuine, one counterfeit. Study them side by side.
Read the Clues
Four diagnostic clues appear one at a time. Each points to a real tell collectors use.
