I need some help regarding some chips I have. I believe they are from an old casino that used to be in the Cleveland Ohio area in the 1920-1940's called the Pettibone Club. Started by Moe Dalitz and the "Cleveland Mafia". The chips are in denominations of $1, $5, and $10. I was given them by someone I consider as a truted source and he said this is where they are from. They do have a "P" on the front side of the chip. Does anyone know of someone who could help me verify that these are from the Pettibone Club?
