The American Gold Buffalo coin series is the only 24-karat gold coin the US Mint has to offer. While the American Gold Eagle is also a heavy hitter, it is considered only 22-karats because of the copper/silver alloy used to make its surface more durable. Due to the Presidential $1 Coin Act of 2005, the US Mint was mandated to produce a 24-karat gold coin that carries the legal tender value of $50 and has a mintage limit up to 300,000 coins. The American Gold Buffalo was first released on July 13, 2006 and avid collectors have never looked back. The American Gold Buffalo collection still stands as the only pure gold coin produced in the US.
