50 Cent Coin

I have a 50 Cent Coin that has a mint error on the edge and also on the front and back of it. The edge is smooth but you can almost see where the milled edge should be. On the back side of the coin you can only barely see the stars around the edge and the design of the Harp is missing the coin itself is smooth, on the front side of the coin you can’t see the stars or Cent writing properly.
