Where can you cash in old coin currency in Atlanta?
If by "cash in" you mean convert to bills at face value, before
I did that I would try to find out if anything in your collection
is worth a premium. You'll need to look at a site such as
http://www.coinclub.com/prices/ to get an idea. If there's anything
made of silver, for example, it'll be worth several times its face
value so you wouldn't want to get 100 cents on the dollar from a
bank. If you're referring to selling the coins for their metal or
numismatic value, I'll have to defer to the other experts who are
familiar with the Atlanta area.
