Silver Dimes, Quarters, Half Dollars -- and most of all Morgan and Peace Dollars -- fueled the U.S. economy ever since huge deposits of precious silver were discovered in the Comstock Lode in Nevada in 1859. Today, this long-lost silver pocket change is highly collectible. You’ll find single coins from silver half dimes to the 2001 Silver Buffalos, sets of Morgan dollars and Peace dollars, and coins graded by PCGS and NGC.
