What This Coin Looks Like (Obverse, Reverse, Mint Mark Location, Special Features, etc.): This is a 1883 3/2 Overdate Shield Nickel error. The 1883 date was stamped on top of the 1882 date which resulted in a 3 being stamped over a subtle 2. The 2 is still legible and is depicted by the arrows in the example image of the coin above.
