Can anyone help me identify this Lego piece?

I've been trying to identify this particular Lego piece so I can order one just like it. Can anyone help me identify which set it may have come from? It may be from a Pirates of the Caribbean set but not for certain. I've included a link to a picture. It's a gold squarish piece with a picture of a skull in the middle.
