Hi Everyone, I have seen different ones mention a black uv light. I have some dumb questions. Why do you check chips? What do you look for? Are all chips marked? How do you know if the chip is marked and the marking can only be seen with a uv light? Are all denominations marked? Are limited chips marked? Is there a site that explains this or tells what chips are marked and what to look for? I know you all have probably fell out of your chairs laughing by now so when you get out of the floor and get your composure back please help me out. Who knows, maybe I am not the only one that is curious about this and has no idea. lol Maybe one of our "newbies" might find it interesting to. Sorry for being so dumb, but I tried to find something in Google about it but evidently I didn't type in the right thing. Thank you for your help and have a great night, Mark
