Mrdrae Valued Member United States 63 Posts	Posted 03/31/2021 10:13 pm I hope delamination is the correct term for this anomaly. This coin has thin lines of zinc exposed right on the edge of many devices. I will only post a few of the pictures I took because there are many. If requested I will post some of the others.

Mrdrae Valued Member United States 63 Posts	Posted 03/31/2021 10:38 pm Split plating is a new term for me. I have found that it means that the copper lamination was stretched too thin, and it splits when struck exposing the zinc underneath. I paraphrased that from ERROR-REF.COM. Thanks for pointing me in the right direction. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 04/01/2021 12:44 am Actually the plating was normal, but the strike stretched it, or Machine Doubling stretched it. This is not a good thing. The oxygen starts zinc rot. Time clock is counting down on this coin. Spender. Edited by coop 04/01/2021 3:32 pm Report this Post to the Staff

Scuba1 Valued Member United States 356 Posts	Posted 04/01/2021 1:16 pm Here's a great link I believe John1 supplied on another post recently that I have personally bookmarked and saved due to the great info referencing true doubling, and not true doubling, and it also has a short spiel on split platting which is shown on a mint mark in the article but also applies to all the outer devices on Zinc Linc's (meaning split plating). And I believe I'm quoting coop correctly in that all Zincolns that show split plating will show it facing toward the outside rim of the cent regardless of where it occurs on the zinc cent.... correct me if I am wrong.... Hope this helps. https://koinpro.tripod.com/Articles...Doubling.htm Edited by Scuba1 04/01/2021 1:19 pm Report this Post to the Staff
