Thaks Roy, now I know I've got to get one of those microscopes or find out what kind of light Greg has. Great pictures and true colors.

By the way, the chips in your messages are 50c white H&C, from Lac Courte Oreilles casino Wisconsin. I have two of the same UV markings and am missing the one on the left. The right two are not only diferent UV but the color of the Indians face and the printing on the chip are different colors. That would lead me to believe they are different lots.

The one on the far right was the first I got and has the smaller UV H&C, (this smaller marking seems to be on older chips) the second was the Large marking just under the chin. That is only my association, the image on the left could have come after or before image #2.
