Hi!
I'm collecting 90% silver as survival money and a silver hedge. I just got a 1/4 bag of mixed 1/2 dollar coins and there were about 35 or so really shinny Kennedy's dated post 1965. The seller sez "they are circulated proof coins and are 90& silver. They weigh about 12.6 grams each as do my 65 Franklin's and they show no signs of being clad coins at the edges. Does anyone know if such coins exist? I got a 1/4 + bag of quarters from the same source and it contained 2 Jamaican dime in it and I'm beginning to wonder if I'm going to the wrong place to do business

. Thanks for any help you can provide.
