Been on that side of the counter before and that was something that always made me tense up. Over 4 years (now this is only counting stuff people actually handed to me, I'm not counting the stuff I found IN the register), I got a couple of silver Roosies, a Mercury dime (almost got a second, but the guy that almost gave it to me was a very good friend and I told him not to spend it), several silver war nickels, countless wheats, a 1964 proof nickel, and a clad proof state quarter.
