ANACS

ANACS was established by the American Numismatic Association (ANA) in 1972 to authenticate coins and identify counterfeits. It certified its first coin on June 15, 1972, and moved to Colorado Springs in 1976. In 1979, ANACS also began grading coins, initially assigning separate grades to the obverse and reverse. Its findings were recorded on photo certificates showing both sides of a coin. The transition to tamper-evident plastic holders began in 1989, and in 1990 the ANA sold ANACS to Amos Press, publisher of Coin World.
