not to speculate but sometimes it is very hard not to. I understand that without possitive proof it is pure speculation BUT these were sold to me as JOCKEY CLUB by the same old Kentucky chip guy that sent me the 255 CLUB chips and some other Kentucky gems. He swore up and down they were Jockey Club chips but with no hard fact proof it is just that...speculation. Still it makes sense that they would have more than one denomination chip in the club doesn't it? I bought his story and a short stack of each.
