John,
Ok, I see what you mean now. That seems like it would be a LOT harder to detect than I thought. By the way, I have access to a pentigraph machine & also tusks of ivory. It will be a LONG time coming & a very big undertaking, but I do plan on making some ivory chips. NO, not fakes, these will be orignal modern day ivories & I also have a couple of local Casinos interested in working with me on these...........Andy - Las Vegas
