I've been collecting coins for a long time but I usually collect the ones that have different images on the "tails" side of the coin. I do have some pennies and nickels from as early as 1924 I think it was, and a Canadian half penny.



My grandmother has a coin where the Queen's bra strap is showing on the coin. Figured those were pulled pretty quick! (I think it was a coin, maybe a one dollar bill)
