I am one of them. A good "mail" friend of mine by the name of Nelson was a big collector; don't know what happened to him. When I was an AUSA and Judge's law clerk played at the then illegal casinos (do not ask what an AUSA or Judge's law clerk was doing at an illegal casino but he went where his buddy FBI and Court reporters went ). I am missing a few chips but have tried to get one of each of the $1 & $5 chips.
