Awhile back I posted that the gray chips I picked up were chips made at Sharkey's (no implications). The seller told me that they used to cover other chips and make them Sharkey's chips. Yesterday I picked up the black/yellow chips and noted the center labgel core cover was a circle over an irregular lable core cover. I peeled back the top circle and found the King's Crown label. Since there was no value on the Sharkey's I guess the black/yellow was used as a roulette chip? Anyway is this a standard practice and acceptable practice?
