"In regular use coins, unless they are something rare and special, they aren't worth much more than face value. Even case enclosed mint sets, aren't worth all that much, though more than face value."
I'm sitting here with the '04 "Red Book" in my lap. :) Wanna try that one again? ;)
I have RED books and BLUE books ( just not current ones ), and unless things have changed radically, of late, used/worn/in circulation currency isn't worth all that much, if not extremely rare.
