Definite lam on the reverse, obverse looks like it as well. To bad that the coin has been so heavily cleaned. I don't mind still a great find and just to have it for the collection very cool |

the coin has been so heavily cleaned Was clean no doubt. to you to understand: 1. Cleaning a cooper coin will not bring yellow color on one side and reddish (normal) on the other. 2. Second come to what you want to be: "Lamination" (lamination mean union of two materials by different process like press) Ex-foliation mean separation of the material due to a rolling process, which apply in the production of the coins. 3. What you thing to be it is more an linear molecular material structure. It is characteristic for alloy with bigger % of zinc then 5%. Is happened that the alloy was improper mix or because has to much carbon accumulation. |

Weight? The coin looks odd to me Idly I always forget to weight my coins John lol it weighs 2.64 grams so maybe a spilt Planchet with a reverse lamination error? And possible half a spilt Planchet considering those "lines" in the front where it broke away in certain places? Edited by gorham_collector

I do not think it is a split planchet issue. Need a few pros to chime in. John1 |

John I'll have to take a pic of the rim once I'm home from work. I'll post it in a Facebook group which mike diamond and a couple more pros reside to see what they say

I did not expect to see this Interesting reply from mike diamond. I'll look more when I get home at it to see if what he said makes sense. My brain could playing tricks but I'm pretty sure the reverse is just very circulated and worn old scrapes with along with the reverse lamination. For sure. I don't think it looks like chemically or damaged eaten coin. I'll take what he says into consideration tho rim pic at 2:30am  |

Congrats have Mike (the living coins encyclopedia) on your Facebook, and also thanks to post his answer because I learn how to wrote here.
EX: "Mechanical and chemical damage" instead of "linear molecular material structure" and also "eaten material" which it is a laboratory term for action due to the expose of the materials to different corrosive agents.
Nice and thanks.

when you took the sides photos, the last one show clear external agent actions on your coin.
What Mike say "Mechanical" in my opinion it is a split planchet which it is not necessary been total. Is no science evidences that a split in the material structure due to a mechanical applied forces must be total. Could be surface, like could be internal which will can come out long time after fabrication.
Very interesting and nice topic.

External agents I'd say more like common goo and dirty crap you see on wheat cents all the time I've got lots of wheat cents with black whatever on there from being in circulation. And I also want it to be clear to everyone I'm not one of those collectors that says oh I have the million dollar coin etc. I genuinely believe with my experience I do have something I want to understand it more and I don't believe that it's all chemical and mechanical damage ( PMD) |
