Gold American Buffalo bullion coins are the first .9999 fine (24 kt) gold coins ever made by the US Mint. They are legal tender and have a face value of $50. The US government guarantees their weight (31.108 grams), content (1 troy ounce of pure gold) and purity (99.99% pure). They are distributed the same as gold American Eagle bullion coins, and are struck at the West Point facility. In 2006 and 2007 only $50 1-oz. coins were made, but in 2008 the US Mint also made the Gold American Buffalo coins available in half-ounce ($25 face value), quarter-ounce ($10 face value) and tenth-ounce ($5 face value) pieces in Proof and Uncirculated. Gold Buffalos were produced individually and in sets. Purchasing Certified PCGS or NGC Gold Buffalos from Modern Coin Wholesale, Inc. is the best way to make sure you are receiving accurately graded top quality coins.
