I surveyed close to 25,000 graded T205 cards, here are the results (full data added)

Truly a labor of love. Well done.

Thank you for doing this, it is really insightful and helpful in looking at the set.

Interesting to see how tough Sovereign is. I don’t feel like it’s usually advertised as a rare back.

Here are the 13 "short prints" that come in 3 backs only, Piedmont 25, Hassan 30 and Cycle

Cycles are tough.

last one for now, not sure if anyone came up for a catchy name for this grouping of cards, the "second short prints" that come in 5 backs instead of 3, but are all lower pop and quite difficult. they share the exact same array of backs. the interesting thing about this grouping is that they all have much higher counts of Piedmont 42 backs. The Piedmont 42 back is very tough in general, but all of these cards have at least 9% of their seen examples having a P42 back.

Here is a thread started by Joshua L in 2012 concerning the 22,013 T205 cards he researched, and the various percentages for the backs. It is interesting to note the very large difference in percentage for the Piedmont 25 cards in this 2012 posting, and the SGC article. I assume the SGC article was strictly involving the SGC T205 percentages...?

Also Joshua broke down backs a little more thoroughly, for example percentages for Broadleaf in both Black and Green ink colors.

Here is the link to that thread:

Post # 40 on this thread contains a table another member created that is a little easier to see.
