“Interest in these glittery investments – which soared five years ago – has been especially hot this year. In January, the US Mint sold 7.5 million American Eagle silver bullion coins to dealers – a monthly high, and not far from the 9.9 million silver American Eagles it sold in all of 2007. Demand was so strong that the Mint temporarily ran out of supplies and had to suspend sales for roughly 10 days. In addition, sales of American Eagle gold bullion coins hit highs not seen since June 2010.”
