More BIE Stages, and crossover to Cuds on Coins listings

rmpsrpms

This morning I did a photo sequence study on some 1955-S Cents that are from the same die as the previously studied BA110-123 sequence, which I also discovered had an earlier stage that I'm calling BA109. While that was complicated enough, turns out this die has much more to offer! The latest photos show even earlier stages, and these stages also crossover to a reverse die that broke early in the life of the obverse, and created some listed Pre-CUD breaks. From what I know at this point, here is the sequence:

Stage BA110-5, tiny chip corner of E, die crack in R wheat
Stage BA110-4, Pre-CUD die break, crosses over to PC-1C-1955S-13R
Stage BA110-3, larger Pre-CUD die break, crosses over to PC-1C-1955S-10R Stage A
Stage BA110-2, additional pre-CUD die break, crosses over to PC-1C-1955S-10R Stage B
Reverse Die changed
"BA109", documented in previous thread
Cohen BA110, with die chip on E and small die chip on B with die crack linking them
Reverse Die changed
Cohen BA111 with die crack becoming die break
Cohen BA114-123, with progressively larger BIE, large chip in the 9, and reverse die cracks

I created an animation of the 4 pre-CUD stages, see below. I find it interesting to see how the die cracks, breaks, then is displaced a bit to form the Pre-CUD. I suspect the piece of die broke completely away shortly after the last stage, although the actual CUD is not known.

Got a few retained cuds that along time ago, 1971, corresponded with Mort Goodman on per his book on cuds.

Pretty neat visual.

I think that I have to credit Frank Spadone's book for first making me aware of such things. My how this specialty has evolved over the past half century.

Love the visual. It is simply amazing.
Is it possible to slow down the progression so it does not refresh so fast?
Thanks

Here's a different animation, with longer time at each stage, and going back immediately rather than back through the middle stages. So rather than:
1-2-3-4-3-2-1-2-3-4

it goes:
1-2-3-4-1-2-3-4

Is this better?

Much better and thank you for addressing my request.

You're welcome. I use the ezgif.com online animation tool, so it's fairly easy to create the animations. The images that go into them take a lot longer, though!
