Yes, I have several with the embossed stamp, more than I have of the plain one. Given the total print run of 15,000, I doubt that it is particularly scarce either way.
I don't have any knowledge of how they were distributed. Absent that information, the embossing is just an after-the-fact addition to the card and as such, is not listable as a separate variation.
