If you are opinion of buying gold and end up with 1-oz American Eagle coins, it would be difficult for anyone to say that you could have done better. These U.S. Mint products have become the most popular one-ounce bullion coins in the world.Gold Eagles, as they are commonly called, were introduced in 1986, and they were unique to the U.S. Mint, being the first 1-oz bullion coins ever minted by the Mint. Further, they were the first 22-karat (91.67% pure) precious metals coins ever minted by the Mint. Because of the copper added to make the coins 22-karat, the gross weight of the 1-oz Eagle is 1.0909 oz.Today, 1-oz Eagles dominate the new gold bullion coin market in the U.S., claiming some 80% of the market. Since their beginning in 1986, nearly 12 million have been sold. In 2008, the Mint sold 710,000, but through the first nine months of 2009 the Mint sold right at 940,000.
