In January 2014, a private firm on behalf of the Mint, began surveying customers on possible options for a special issue of the half dollar in commemoration of its 50th anniversary. In June, the Mint announced plans to issue seven special 2014 Kennedy half dollars in commemoration of the series' fiftieth anniversary: two in clad, from Philadelphia and Denver, four in silver from Philadelphia, Denver, San Francisco, and the West Point Mint, and one in .9999 gold, from West Point. The clad and silver versions bear the normal date; the gold coin has the double date 1964–2014. All have higher relief than the usual issues. The gold coins were released in conjunction with the American Numismatic Association convention in Rosemont, Illinois on August 5, 2014.
