It sold for a few dollars in a novelty shop because it's a manufactured item called a "magician's coin", not a mint error. However a coin collector won't pay you anything for it because it's made by cutting up two real coins and swapping sides, meaning it's both damaged and altered.

If it's silver, then at least $30.00
