I love those half dollar sized Washington quarters!

I also love the .999 fine, 1 ounce buffalo nickels

Sooooo, in a bit more time, the answer to your question will be, any silver is silver. Be glad you found any.
And, right now i just find out what my local store has, and the best deal is, of what they have.

I gladly take junk silver. Not only is it a ticket to ride the silver moon mars shot, if we have a collapse of dollar, junk silver is still easily recognizable, and will get you something without having to break an ounce.
