These are driving me crazy. I am looking at some chips and I just can not tell which one I have. Why do casino's have these different versions? The chip guide tells me that mount airy has all three versions lcv, scv, and lcv/scv. The casino just started using chips in 2010 so I would think these are all first issues so why the 3 different types? Would I expect to see all 3 in use at the same time?
