1936-D San Diego, California Pacific International Exposition. MS-66 (PCGS).，Soft satin luster is seen on both sides of this silky smooth, virtually brilliant Gem. A second authorizing Act, this one dated May 6, 1936, resulted in the Denver Mint striking an additional 180,000 San Diego commemorative half dollars bearing that date. Interestingly, this mintage matches the number of examples of the 1935-S issue that were returned to the San Francisco Mint to be melted. Sales for the 1936-D issue also failed to live up to expectations with 150,000 pieces melted for a net mintage of 30,000 coins.，From the A.J. Vanderbilt Collection.，
