24 karat gold bars are seen at the United States West Point Mint facility in West Point, New York June 5, 2013. Demand for U.S. gold coins is still at «unprecedented» high levels almost two months after an historic sell-off in gold released years of pent-up demand from retail investors, the head the U.S. Mint said on Wednesday.
