Errers and Varietys Bedrock of the Community United States 73900 Posts	Posted 01/10/2018 9:40 pm I found all 6 of these from a OBW BU rolls of 1973 D Lincoln Memorial Cents. I wanted to share the different stages of progressions of the Sunken Die error. As you can see, it gets worse every time the die strikes blank planchets. The die steel sinks in more every time it strikes a blank planchet. Moderators, I hope it's okay to post this as it's showing different stages on how this error progresses. I know I posted a coin with this error not that long ago, but this is just showing the stages of progressions. Errers and Varietys.

Errers and Varietys Bedrock of the Community United States 73900 Posts	Posted 01/11/2018 12:02 pm They do look like a Die Clash, but they are not though. This is a mysterious case of die failure.

Biedercoins Pillar of the Community United States 1601 Posts	Posted 01/11/2018 1:48 pm Wow, that is really dramatic! And these all came from a single roll? Did you go through other rolls? I've had the assumption that coins get bagged at the mint, then rolled when they were distributed to FR banks or (today) other large banks. If I weren't so dang lazy I'd go downstairs and see if I had rolls of '73D rolls to go through. Just got over a combination of Flu & a GI bug, though, and just getting off this couch for hydration takes a real force of will. Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 73900 Posts	Posted 01/11/2018 2:10 pm These came from all three OBW BU rolls. I went through all of three rolls that I bought on ebay. Hopefully, you will stay strong and won't get badly sick again. Errers and Varietys. Edited by Errers and Varietys 01/11/2018 2:13 pm Report this Post to the Staff
Biedercoins Pillar of the Community United States 1601 Posts	Posted 01/11/2018 4:20 pm Thanks, E&V. Perhaps you're recommending a nap? I think that sounds like a plan. BTW, did the rolls have a stamp or other ID of where they came from? Must have been the same origin. Later, Zzzzz... Report this Post to the Staff
Jim0815 Pillar of the Community United States 5238 Posts	Posted 01/11/2018 4:23 pm I have seven of those in different stages. I believe they still don't know why this was caused. Report this Post to the Staff

The rolls didn't have an ID of where they came from, but it must of been the same origin. See you later, have a good nap. Quote: I have seven of those in different stages. I believe they still don't know why this was caused. Yep, they still don't really know what caused this mysterious form of die failure. These are very fun to collect so if you find them, save them. One good guess is maybe they didn't soften the workstock (something that I saw Coop saying on a similar thread with the same Sunken Die error). Errers and Varietys.

CoinCents Pillar of the Community United States 3656 Posts	Posted 01/11/2018 9:45 pm This is a really interesting post E&V I am going to have to book mark it. I would have thought in seeing your images that the LC's were suffering from VLDS (ghosting) Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 73900 Posts	Posted 01/11/2018 9:57 pm Thank you CoinCents. What happened here is the die steel in for some reason. This is a mysterious form of Die Failure. They still don't know what causes it. Maybe they didn't soften the die? Errers and Varietys. Report this Post to the Staff
CoinCents Pillar of the Community United States 3656 Posts	Posted 01/11/2018 10:18 pm Really, really interesting. I have the error-ref webpage marked as well. Thanks for posting this. From what I am getting from the Error-ref website is that this area is abnormally soft. Edited by CoinCents 01/11/2018 10:24 pm Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 73900 Posts	Posted 01/11/2018 10:39 pm It is very interesting. You're welcome. The area is soft and it is all distorted looking. Errers and Varietys. Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 73900 Posts	Posted 05/25/2018 12:00 am Has anybody else found these from OBW rolls of 1973 D Lincoln Memorial Cents? I'm sorry to bring this topic back up again, but I think it would be a good discussion. Errers and Varietys. Report this Post to the Staff
NewMember Valued Member United States 274 Posts	Posted 05/25/2018 12:20 am "Maybe they didn't soften the die?" E&V, did you mean harden the die? If I'm not mistaken, there were multiple dies used with the same hallmark? It would be interesting to find the markers and trace backwards to the commonality. Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 73900 Posts	Posted 05/25/2018 12:39 am NewMember, I think that's what I meant. Hardening the dies. It would be very cool to find the die markers and trace back to what caused it. It's still a mystery to what has caused this reccuring Sunken Die error (Die Subsidence). Errers and Varietys.

stoneman227 Pillar of the Community United States 2376 Posts	Posted 05/25/2018 06:45 am E&V , I just now noticed this post. Thanks for bringing it back ! Since these were found in the same roll , they were struck during a limited time span. That said , going by die scratches as markers , it appears you have three different reverse dies illustrated. Photos 1and 2 are of the same die. Photos 3,5 and 6 are a different die and photo 4 is from a third die. If you check the obverses of these coins you may be able to confirm this. As time allows I have been looking into this anomaly and have examples from different years , denominations , as well as types of errors that I feel stem from the same root problem.
