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."
