Imitation Pre-1950 Coinage
"The United States Mint is aware of recent reports that some companies in China are producing unmarked imitations of pre-1950 United States coins and are selling them on-line. This practice not only exploits unwary consumers and collectors, but also may violate Federal law. Both consumers and coin collectors should be aware of this practice and should exercise vigilance and good judgment when purchasing pre-1950 coins."
