IMHO, most likely you are going to get the short end if you go to a pawn shop. The "best" that you could hope for is $10-$12 apiece. Silver is trading today at $18.00/ozt, and the .6 ozt silver centers would be $10.80 melt value.

However, if you are willing to take $10 apiece, you can try a pawn shop and see what they say.
