Jim I have one of those Halloween Black Lights (19 inch size) that can pretty much light up a whole room. I pulled all of the Win Card Chips out and gave them all a once over.....that's why I know there were only 1 of most of the chips I was looking at. Most Win Card Chip don't have UV makers. I guess I need to now updated that in my spreadsheet .

I think my wife thought I was a "nut" last night, I had to use her camera....she has a one that can take close up pictures
