Thanks for the comments, Cataloging dies and marriages, as you well know, is a daunting task. I put a ton of caveats and disclaimers on this section in terms of omissions, errors and repeats. JD and I spent a whole week on a single proof die trying to determine if it was unique or a repeat. On the big mintage years/mintmarks, 77-S, 78-S, 77, 76-S, it was a best effort approach. I could spend a year on each and not get them all. I suspect that there might be a few dies and die marriages that were shipped to Asia and never circulated in the US. It was quite surprising the number of rare (some being extremely rare) TD varieties that have been found with chopmarks. On smaller mintage dates/mintages, this section is more accurate (but still not 100%). But, you know that!!!
Please reach out of you have questions on anything,

Got mine and perused it. Outstanding work and presentation!
I will have to try to correlate the listings within it, for dies and die pairs, with my own catalogue to see if I missed any important ones. (My approach was strictly to catalog all of the dies and pairs, like the VAM listings, with less regard for rarity, though that became evident in many cases and through discussions here.)
If you do that, then the minute (?) changes mentioned in the middle of the series may need to be broken down further. I own less than 10 of these coins and there are some naked eye differences.
One more thought. Many years ago, the late Bill Cowburn wrote an article on the Gobrecht Journal on cataloging 77-S dies. (I used and cited his methodology.). I went back when I was complete and tried to cross reference to his listing. I got about 90% there with some big question marks on the remainder. If you have two physical coins in front of you, not that hard on some coins. If you have two great images in front of you, it gets harder. Partial images, it can be very hard or impossible. On all of these, coin-to-coin die states and striking anomalies can be a bear.

Thanks for the ideas. I'll likely do a quick listing in the Gobrecht Journal and talk to the LSCC about a Baltimore presentation. Best, keoj
Can you get a Vendor, or maybe LSCC, to have your book available at ANA in Aug.?

But again, you know this and lived it.

There are still a few on my wishlist but here are some fun ones that have surfaced recently.
75-Very Wide c c (only chopped example, one of five known in any condition)
76-P 1/1 w/ Period, Perfect Reverse (only chopped example, one of a few dozen speculated to exist in any condition)
76-P 2/2 (one of five known chopped examples, one of a few dozen speculated to exist in any condition)
