I'm curious on what type of errors it could possibly have. I thought at first the damage was caused after the minting process but after a second opinion they pointed out that on the front and reverse where it has indentations, by the date for example, it shows the 1966 on both the indented side and the side that is not indented. There are also many more spots of interest, any help and info would be greatly appreciated, I can provide more pictures if needed.
