I would think that many of these variations are due to printing variations and/or mistakes. I had two of the $1 Dunes Sultan chips -- one with the colors all lined up within the black outlines & another where the colors overlapped the black outlines by quite a bit. Would these be variations with different TCR numbers or just the result of an imperfect printing process?
At this rate, TCR will be two volumes again very soon. It's either that, or you'll make the print smaller, in which case, I want the table next to yours so I can sell magnifying glasses.
