I have gone over most of my collection with a black light to see the images it produces. I was quite surprised at the results. Most of the newer Paulson's have a larger H/C in the center the older ones have a small H/C off to one side. I wonder when they changed the size. The new Commerce Park Year of the Snake has PAULSON across the center. I also found on my Foxwoods chips the letters MPGE accross the center, I don't know what that stands for. My Venetian H/C says The Venetian. The Bud Jones chips I have all seem to use the same BJ on all the chips. Now if I can just figure out how to scan with some blacklight. Just thought I would share. Thanks for looking.
