WARNING: Millions of dollars in counterfeit coins and bullion enter the market every year. Chinese factories sell fakes on AliExpress for $2 each. Learn to protect yourself.

The Fake Coin Epidemic

A 2012 Manhattan dealer discovered ten tungsten-cored 10 oz gold bars in his inventory — over $180,000 in counterfeits that had passed his initial screening. In 2017, a gold bar certified by the Royal Canadian Mint turned out to contain a tungsten core. On AliExpress right now, you can buy a fake American Silver Eagle for $1.50 shipped. The counterfeit precious metals problem is industrial in scale, and the fakes are getting better every year. This site documents the problem and teaches you how to protect yourself.

Numismatic counterfeits target the collector premium — a $2 fake 1893-S Morgan sold as a $5,000 rarity.
