This is the only example of this chip I know of. It sold in auction some years ago at a high price.
The reverse is blank. It does not have a missing inlay, it never had an inlay on the back, the back is smooth.
It is listed (but unpriced) in TCR. This example is the one that was respnsible for the listing but I suspect the previous authors never saw a scan of the back to know it was one-sided. It is not listed in James' book.

Questions. How could this be? It was suggested it was a baccarat shoe chip. I doubt they would have used a high denom if that was the case.
Is this a genuine error? Does anyone else have one the same?
Does anyone have the chip with inlay both sides?

In fact, is anyone else aware of any other example(s) existing?

This chip will be for sale, and Im willing to look at serious offers now. I havnt made my mind up on price yet.
