Rich,

I'm not sure about the TCR values or designations, but according to the Official U.S. Chip Guide (Campiglia & Wells), the Las Vegas $5 Del Webb's Mint Hotel chip is a 9th issue. Below is the following listed info for this chip:

9th Issue -- 5.00 Denomination -- Maroon Color -- H&C Mold -- 3yel3org Inserts -- HUB-white Inlay -- R4 Rarity with AVG Value @ 20, S-U Value @ 30, NEW Value @ 40

I hope this helps...

Regards,
Thomas (R-7788)
