I would dissent with the popular opinion. I would bet that this is a true error chip. Being two continents apart doesn't mean a thing if the two original chips were made about the same time. As mentioned before, the metal centers are two separate peices, easy mixed up in manufacturing. I think that you have a really nice find, and if it were 2 Nevada casinos the value would be $250.00 to $500.00. I have seen Christy Jones and Paulson chips that have the wrong inlay in them.

Best of luck,
