This one may not have been approved but it was used.
When the SantaFe opened in 1991, a poker dealer by the name of James (RJ) Porter received this chip as a toke. RJ is now a prop player at the Texas Station. I was a friend of the casino manager Joe Cordeno & he had the cage manager verify there were no more in the cage.
I believe this chip was brought in by a salesman & left in play. This is much like the Venetion House Mold $5 chip, but I believe only one was brought in. Until I see another one I beleive this is a very (no I will not say the "R" word) good chip.
