The Reno CC set has JR on them.
I have something you might be interested in.
The 6 chip CC Reno set that has been glued together to perfectly align the rim puzzle. It looks like they have been glued for life. But who knows when it comes to glue.

I also have the FQ's 1998 4 chip Halloween set, the same way. Also the Circus Circus 30 year anniversary 6 chip set.
If I can figure out a way, I will scan them.
