Scot ReaderTed, Brian:
Consider the following:
1. There are more T206 subjects depicting Chase (5) than Cobb (4).
2. There are more superprints of Chase (2) than Cobb (1).
3. ATC was located in New York--where of course Chase played.
My guess is that all six superprinted subjects enjoyed very similar print runs.
[And in my experience watching eBay, Chase (Dark Cap) is just about as ubiquitous as Cobb (Red)].

Edited to add: Also, Ted, you have (quite impressively) been able to acquire all superprints with Sovereign 460 EXCEPT Cobb (Red). I believe this would hint, at least, that Cobb (Red) was printed in no greater numbers than the other superprints.
