This chip, to my understanding, has has been reguarded as a rare/hard to find addition to riverboat collections.There are currently two on Ebay,by different sellers. I emailed one of thesellers to inquire as to how many he had and his answer was "just over 50". Does anyone know if the casino has started using these chips again? The seller was asking $40.00 to start the bidding so I assume he understood the rariety. The other seller had his amidst a group of other $1.00 chips at a common low price w/ no mention of this chip 'in particular'.If nothing else, maybe this info. is of some enlightenment to other R.B. collectors.
