International Gold 80 Trio
The International Gold 80 Trio was a limited edition trio of gold coins released by the United States Mint in 1980. The coins were the one-half ounce, one ounce, and one-tenth ounce American Gold Eagle coins. They were the first gold coins issued by the United States Mint since 1933, and they were the first to be issued in metric sizes.
The coins were minted in proof condition and were struck at the San Francisco Mint. The obverse of each coin features the classic Saint-Gaudens Liberty design, which was originally used on the gold coins from 1907 to 1933. The reverse of each coin features an eagle in flight, which was designed by Augustus Saint-Gaudens.
The coins were extremely popular when they were released, and they quickly sold out. They have since become highly sought-after by collectors, and they are considered to be one of the most important modern gold coin issues.
