"My point is that I wasn't making stuff up as I went along, the ENDY's said they were never in the paulson store, and added that they may very well have been made as a sample run for a casino or for a gift."

Did you speak with the Endy's? They could say for sure that the chips were never for sale in the store but couldn't say for sure why they were made? Do you really wonder why a reasonable person might question any or all of this?
