Have wondered about Rogels

The "B" rack was retired with the start of the 2018 WSOP and replaced with a new rack with a custom chip mold that reads "WORLD SERIES OF POKER" instead of the traditional hat & cane mold found on most Paulson chips.
Sounds like Harrah's Marina. They replaced most denominations with clay chips, but still have some odd denominations, like the $2.50 and $20 chips, of the Coin-In-Center type.
I think they still use pink $2.50 chips with a silver coin inserted in Atlantic City at either Harrahs or the Tropicana. (I know I've used them somewhere in the North East within the last year ) Enjoyed reading.
These stories are great. I've been sharing them with friends. Keep it up
