Paul, I am an error chip collector. Maybe most of us are. I have 12 different chips that were delivered with inlays on only one side. I have never tried to trade or sell any of them. They are worth more to me. I see the problem as, how do you convince someone else they were delivered that way. Inlays can be taken off. I also keep chips that have cockeyed inlays, if they are real cockeyed. Again never tried to trade one.

I do have other errors that I have been offered a lot of money for. One casino on one side and a 2nd casino on the obverse. I also have 9 chips with one denomination on one side a second denomination on the obverse. I guess these are the true error chips as they would be hard to make in the garage workshop, but again I have never tried to sell them. I also collect counterfits if you ever run across any.
