JDRMCB Pillar of the Community United States 615 Posts	Posted 02/14/2026 10:25 am There's something going on with this 1973-D Lincoln Cent within, above, and below the first few bays of the memorial on the reverse. If it's some sort of die clash, which kind is it? So I can narrow down my research window... Thanks in advance!!! Report this Post to the Staff

-makecents- Pillar of the Community United States 8731 Posts	Posted 02/14/2026 11:01 am Fun find. There are at least eight different dies know, probably a lot more. I always put them aside and plan on seperating them someday, by dies. -makecents- Report this Post to the Staff

Seeker_101 Pillar of the Community United States 1791 Posts	Posted 02/14/2026 6:32 pm Interesting!! I learned something new today! I would assume though the the affected dies all came from the same piece of bar stock cut to length one after the other. Just the machinist in me coming out. Report this Post to the Staff

I do not think so, because we would be dealing with hundreds of thousands of coins, if not millions. If you read the link that was left, there was more than likely issues for a time with the annealing process and the fact that it occurs in the same exact spot is an oddity too. I do not think anyone has a perfect answer at this point. -makecents- Report this Post to the Staff
Seeker_101 Pillar of the Community United States 1791 Posts	Posted 02/15/2026 12:13 am Thank you Makecents. I realized I was wrong shortly after posting the comment because the only way it could be in the same spot would be at the end of the heat treating process, typically tempering. Tempering relieves the stress induced from hardening making the metal less brittle. So there are really only 2 possibilities. The first being, that area never hardened to where it should have such as being in contact with something that acted like a heat sink. Or the 2nd being that a problem in the tempering where the die developed a hot spot and got far hotter than it should have causing an annealing effect. Report this Post to the Staff
