I got a notched set 5/25/100 from Florida Bob Ginsberg while visiting him in FL in 2000.
Rest easy friend.
Bob was one of the biggest FL chip collectors. If it crossed FL borders he wanted it.
I am pretty sure he got them from the FL Paulson rep. PS used to have a store in FL. Bob got a ton of his samples when they closed.

Bob told me the chips were delivered to Cunard Cruise lines in Fl.
After a BB inquirey about the chips:
I had Paulson records checked. They confirmed.
