I personally don't like the way the digital images come out. Real photos are better. It's expensive. Just to save some research, here's what I came up with. It may not be perfect, so anyone who tries this needs to take some experimental photos for themself. This is what I found, after bracketing shots and taking a dozen pictures using two 10w flourescent lights abouttwo inches away lighting from the sides. Camera at f3.5, 1/8th second exposure, ASA 200 film. 1/4 sec. was just as good. (can't find the scan right now, but I'll look)

Almost all Paulson chips have some variety of the H&C on the chips now. Even the new Casino de Ithmus City! Most LEs have a larger overprint, there is a medium size, in a couple of colors, and I have found a small imprint in three different colors.

If you get a light, try a Golden Nuggett for a really big UV image. It's repeated over and over across the entire chip. I think Caesars Palace had one like this as well. Not too many Chipcos, but the ones they do have are interesting. I'm not sure about Bud Jones, but the ones I have found are simply "BJ" and nothing fancy that I've seen.
