For the time it would take me to examine every nickle and penny in my giant jar to find any real copper or nickel ones, I could go out and shovel two driveways and come out ahead...........
Pennies, if you have a good supply (and way to sell back the new ones) can be sorted as I note in post 127.
gee, I feel so smart now for buying $50 worth of pennies back in 1981....haven’t got a clue why I did it...
