Hi Jerry,
The 50 cent chip you show in your scan has much history. The story goes that Jay Sarno, who originally built Caesars, was walking through the casino and spied the 50 cent chips on the craps table. He walked over to the craps table picked up a couple of stacks of the 50 centers and threw them in the air and the chips landed on the casino floor. He turned to the pit boss and was quoted as saying "Caesars Palace doesn't have 50 cent chips" get rid of them.

It's a GREAT chip and in my opinion worth much more than the $100.00 you are asking.

Jim
