Brandmeister Pillar of the Community United States 6491 Posts	Posted 10/14/2023 11:25 pm Are these parallel lines normal on LMCs? If it were a nickel, I would think it's roller lines, but this coin is plated. Report this Post to the Staff

Errers and Varietys Bedrock of the Community United States 73922 Posts	Posted 10/14/2023 11:52 pm It's a plating issue. It's called Plating Blisters. https://www.error-ref.com/blistered...d%20pressure. Errers and Varietys. Report this Post to the Staff
Brandmeister Pillar of the Community United States 6491 Posts	Posted 10/15/2023 12:00 am Interesting, so plating blisters come in different flavors like circular and linear. That, I didn't know. Thanks, Errers. =) Report this Post to the Staff
silviosi Pillar of the Community Canada 6244 Posts	Posted 10/15/2023 12:16 am I think are plating blister which follow the core of the coin. The core has from unknow reseon some imperfections from rolling. The blisters will show the spaces between the rolling lines of the core where is form air pressure. I saw this in many others countries plated zinc coins. Report this Post to the Staff
Halo1st Pillar of the Community United States 2775 Posts	Posted 10/15/2023 02:36 am The early conception (prior to plating) had thoughts pertaining to the rinse cycle being a bit inadequate for the newly introduced zinc planchets. The result or cause produced many plating issues in the beginning years. Thanks, Doug. Edited by Halo1st 10/15/2023 05:25 am Report this Post to the Staff

John1 Moderator United States 56855 Posts	Posted 10/15/2023 07:57 am Most likely a plating issue. I do wonder though if it might be a rolling issue with the zinc before plating with copper? Also, not normal or intended and not an error or variety.No added value either if you were wondering. John1 Report this Post to the Staff
Coinfrog Bedrock of the Community United States 94367 Posts	Posted 10/15/2023 09:12 am Plating issues abound in this poorly-conceived series. Report this Post to the Staff
Brandmeister Pillar of the Community United States 6491 Posts	Posted 10/15/2023 09:24 am Rolling lines on the zinc sheet seems like a good theory. I checked the back, and sure enough, the lines run in exactly the same direction as the front. Obviously the copper plating didn't like that. Report this Post to the Staff
Dearborn Moderator United States 95432 Posts	Posted 10/15/2023 6:18 pm I'm going with roller lines here, note how they are mirrored on the reverse. There might be some plating issues along with it though. Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.
