Are any of these coins special? (sorry for the unproportional picture coin sizes! thats just how i took the pic) 1 2 3 4
Your four coins are all 90% silver. I don't see any collector value for any of them but they are all worth their silver value which is $29.61 at $27.29/oz.
The 1964 is in nice condition and quite common but you could still get about $8 on eBay. The others are worth scrap which is 23.50 for the others. You don't have a treasure unfortunately but you still got about $30 in coins.
