I found one box mixed of 100 chips in Vegas years ago. For years they were the only ones anyone had seen. All the Playboy collectors really needed the 25. There were 40. Of the other 3, 20 each. I never found any others or had any calls. I have only a couple of each left now. One in my Playboy collection.
They are all beautiful chips & will be absorbed into collections eventually & some day perhaps be thought of as rare again. As mentioned there is that extra demand unlike other London, or any other chips as they are Playboy. I am sure there are 50 collectors who would want these sets. At the right price that is.
