This is what I have found in my till at work so far. Cent 1941 1942 1949 1950 1951 1955 Nickel 1946x2 1952 1954
The nickels are pretty worn out. Nice thing is, the dimes and quarters come in plastic tubes, so I can just look at the side before I open them. I try to carry pennies, nickels, and a quarter with me in case I find something.
I was wondering when you would make this post. Be very sure that it is OK to exchange change, don't want to see you fired for stealing
