*welcome* coin7225 ... sorry, I don't recognize it either (any chance you could give us slightly better photos and perhaps its weight and diameter and metal type, etc, etc ... is it magnetic? ... is it gold?) good luck Oh, and Happy New Year!!

Sorry about that coin7225. Doug, once again it's amazing how you find these things. Truly awe inspiring.
The coin looked too good to be true unless in the hands of someone who would know it. The original is in the Ashmolean Museum. I Googled fake william conqueror coin and there it was.
