Each of these 2014 Black Diamond Gold Buffalo coins contains 1 oz of pure .9999 fine Gold and is graded a perfect MS-70 by PCGS! When the American Gold Buffalo burst on the scene in 2006, it immediately demanded a place among the world's elite bullion coins. Black Diamond refers to the American bison widely accepted as the model for James Earle Fraser’s Buffalo Nickel reverse. Housed in New York’s Central Park Menagerie, Black Diamond wowed crowds with his majestic mane and sheer size for 20 years. Just like Fraser's design and Black Diamond, the U.S. Mint Gold Buffalo is a true American treasure.
