I have been very lucky with a couple of pawn shops. A couple months ago, I got a nice looking set of war nickels (12 total) for $10. At another small, junky pawn shop where my wife is from, I asked for his price on some silver and ended up having to make a very fast run to an ATM. It was around last Christmas and I asked how much he wanted for a couple Walkers and silver quarters. He said $7 each for the halves and $4 each for the quarters. I bought all he had. I went back later and pulled out about 6 40% halves from his box of random halves for $1 a piece. Very good day for me. That will be the first place I visit next time we go to my wife's parents place- sorry, inlaws.
At another place just a couple weeks ago, I picked up a few silver Canadian quarters for $2.50 each.
You just never know. I always go in and see if they have anything. Usually, I come out empty handed, but every now and then...
