We ALL want a true error chip, but an R-6. What doe's James say about an R-6 75-131 known to exist. Hum wonder how many were issued in the first place. Remember this is an error chip. But what is an error. A mistake by the maufacturer, or a mistake by Harrah's for having a $1. and $2.50 that are so much alike? In any case all brass and Harrah's collectors must have one by now.
