I got the 50¢, $1, $5, and $25 from Bill Akeman when he had his store on Spring Mountain. I never saw the $100 there. That was in 1998.
His story was they were never delivered. I assumed he had the rack.
He had a lot of them. No charge he gave them to me.
I was a regular haunter of the PS retail store and don't remember ever seeing them in there. Anything is possible.

I do have some that says Regent Rainbow under the same logo. I have the $100 in this one. Got them somewhere in 1997.
