I have several cheap commemorative coins my FIL gave me over the years. He was a collector of worthless crap but they are 1 troy ounce of silver. Are they worth anything more than their weight in silver?
Maybe, but usually not. They're circulated, which kills collector value. All you can hope is that 1 or 2 of them have become hot collector's items. Check eBay.
Look at it this way, though - those little cheap coins are worth almost $50 at the moment.
And TAB, as usual, is wrong. The projections are that silver should be running about $60-$80 an ounce right now, but its price is being manipulated. If you need the dollars, sell the silver, otherwise, if it were mine, I would hold it a while longer.
