These TSC chips were acquired with a lot of Union Plaza tournament chips. The seller claimed that they were used at the Plaza but he wasn't sure what the TSC stood for but said the T stood for tournament.
We all know that this "attribution" was a long shot.
Well, last Thursday I ventured to the El Cortez in search of Jackie Gaughan. He typically isn't hard to find and that day was no exception. Jackie was playing poker at the ElCortez. I approached him and asked him if he recognized the TSC chip. He said he didn't. That was the extent of our "conversation". I'm not at all sure that he totally understood what I was asking.....but there it is. Mr. Gaughan couldn't attribute the chips. That's pretty much what I expected but the whole process was interesting.
