Thanks for those scans, Brian. The thicker card I have is similar in color (on the back) to your middle card. I've reviewed the thickness again, though, and it definitely appears to be about twice as thick. I think mine is different because the font is blue. Even in your variations, the font seems pretty dark.

I thought I had saved the picture of the first time I saw one of these but had not thought to look for it. It was actually a card that came in the mail to me and I scanned it but could not find the scan. It had a similar thickness as the Touchstone I've shown here. I sent it back to the seller because I did not think it was legit and he accepted returns. This card has an dark purple ink color in the font, which matches the brim of his hat. I had forgotten all about this card until this discussion prompted me to look for the scan.

Based on the ink colors of yours and the ink color on my Touchstone and this Hendrick, I am inclined to believe these are not authentic. It seems like the authentic ones, while being on a different stock, do not have font color that varies such as these. I am definitely aware that the colors in the pictures can change but don't believe the font colors change.
