I Was So Tempted!

So, in my chemistry class today we were doing experiments on coins, particularly pennies and nickels, (by experimenting I mean measuring them and weighing them). The teacher told us to go get 10 of each denomination from her bags. I get the pennies and I see 4 or 5 wheats looking at me. You guys have no clue how tempted I was to take these coins. I looked at the dates and they were common dates. I didn't take them. I guess that's a drawback from coin roll hunting that I have to look at every coin I come in contact with and have it.
