These chips are attributed to "Pettibone Club" from Cleveland Ohio in Ed Hertels online book of illegals. I found 25 white, 50 yellow, 100 blue, and 100 red. The yellow and white are in new condition. The Red and Blue are used and have some dirt but are in above average condition. they are probably 60-80 years old. They are listed at $10 each. I will sell the set of four for $12 shipped. I can accept PayPal as long as it is not a credit card or personal check from club members. Also I would like to trade personal chips if we haven't already done so. Please send an email if interested.
