A friend and I just started stocking up on silver recently. So far I've grabbed 1oz coins, bars and some 90% quarters. Today I figure I'd go to the bank and grab some half dollars. I bought $100 worth (ten rolls) from them. First roll was full (besides 4 coins) of 1968s. Long story short, out of those ten rolls I found 48 40% coins. I wish they had more but that was all they had. I'm officially hooked now.
