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

The most interesting thing here to me is the Hassan 649 vs. Hassan 30 figures. Factory 30 seems to have been a lower production facility for this brandas whenever Hassan appear in an issue there is a gap in scarcity. Large sample sizes of other non-baseball Hassan sets indicate to me about a 3:1 ratio gap in those sets, 649:30. Interesting that the ratio may be widely different in T205 vs. Hassan’s less popular sets today.

The other thing to consider is how many fronts actually have a given back. For example, the MLs have a Hassan back, but it will always be the 649. Based on what I saw, there are a bunch more fronts where there is a Hassan 30 back (112) than a Hassan 649 (75), but because of those minor leaguers who have disproportionately higher totals I think it impacts the totals. Below in chart form



Sweet Cap Black (25 and 42) are only found on 56 fronts, but they are plentiful on the cards that have them. For example, the Sweet Cap Black is much more populous than the Polar Bear on a card per card basis (22/23 per for SC Black, 14 per for Polar Bear)

Lots of interesting stuff in the data, imo. When I went in, I expected Sovereign and Honest Long Cut to be slightly more rare than they actually ended up being.

Jay thanks for posting that, I hadnt seen it before.

For my purposes, I never split out the AB Green/Black and the Broad Leaf Green/Black because they are mutually exclusive and can't appear in both colors, so it was easier/faster for me to not break them apart in my sheet, but it wouldn't be too hard to do.

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.
