I just picked up a chip at an antique show from the Bonanza Hotel, LV. It is TCR#6722 - $1 ochre/scrown/Ted Fogel promo. The value in TCR is M+ if it is cancelled. There does not appear to be any cancellation marks on the chip. Does anyone know how this chip may have been cancelled? I might be missing something.

Just to let everyone know there are still bargains out there - Price I paid for the chip was $8!!

Thanks
