If one is looking for fractional Silver, checkout out US Silver War Nickels, Five Cents. Their metal content is Copper 56%, Silver 35%, and Manganese 9%. With actual Silver content at 0.0563 troy ounces, it will take about 18 (17.76) to equal one Troy ounce of Silver.
I am always on the lookout for these beauties, in the junk box, that are in better condition. Nickel collecting is all but dead but may have great potential since nickels have over $.041 worth of Copper/Nickel content. Silver Nickels' value have gone from under $1 to $1.37 in less than one month. I have been taking them as the change to round up purchase prices at the LCS, for years, at from $.75 to $1. Thanks for your interest and stack on.
