Yeah its rough but the metal is still the same.

The other day I took a jar full of coins up to the bank. They actually have a Coin Star machine in the branch. Instead of having to roll coins, they pay the fee on the Coin Star so it works out nice. Anyways in the reject coins I find a 1956 quarter. Funny thing is I usually check my coins, so I either missed it or it was left by the last guy...
