2oz of silver for $7... that is a score! I wish my bank would be open to this, but they don't want the coins back, so they frown on the practice.
A few months ago, I received 2 Kennedy halves in change from a store. I wasn't happy about it until I checked the dates and found one to be a 1965.
I'm guessing that I'm not the only one that checks the date on every coin they come in contact with.
Banks have to take them back. Dont let them discurage you from hunting. Keep stacking my friend.
