I did the Binion's search about three years ago and came up with about a dozen sets of the three types. The pic below shows what they look like. I have one complete set left, available at $10 postpaid. I also have a few of the 1st and 3rd chip shown, but the middle one was hard to find. Note that the signature is a different size on the two HORSHU molds and one of them has it outlined in white to make it more readable.
