Member: Seasoned Veteran DWLange Posted November 9, 2020 Member: Seasoned Veteran Share Posted November 9, 2020 That is almost certainly an ordinary cent from which the brass plating has been removed via environmental damage. Modwriter 1 Link to comment Share on other sites More sharing options...
RWB Posted November 9, 2020 Share Posted November 9, 2020 Thanks for the full-coin photos. Much easier to examine Tridmn. New collectors should note the specific, accurate language used by Mr. Lange: "...from which the brass plating has been removed...." The coating on modern cents is an alloy of copper and zinc - with is properly called "brass" and not "copper" as mentioned in the vernacular. Yes, it's a tiny "nit" - but in numismatics details and accurate language are important. Link to comment Share on other sites More sharing options...

The Mint says "copper". Edited November 9, 2020 by VKurtB Link to comment Share on other sites More sharing options...
James_OldeTowne Posted November 10, 2020 Share Posted November 10, 2020 The mint surely wouldn't use "pure copper" as plating - that would be an exceptionally poor choice. Link to comment Share on other sites More sharing options...
1917 Posted November 10, 2020 Share Posted November 10, 2020 well, it has some copper, so in the mint's mind, same thing right? After all, would you be all that surprised if the mint came out with a "silver" coin with only like 10% actual silver content in the alloy?

Tridmn Posted November 10, 2020 Author Share Posted November 10, 2020 Pic is too large, but weight of 85 is 2.45g. Link to comment Share on other sites More sharing options...

The loss of the exterior copper plating exposes the inner zinc-copper alloy core to environmental erosion. Link to comment Share on other sites More sharing options...

I knew the copper plating would take weight off, that's why I posted them; so there would be no confusion. Link to comment Share on other sites More sharing options...

VKurtB Posted November 13, 2020 Share Posted November 13, 2020 (edited) I'm FAIRLY certain @RWB and DWL are incorrect about the brass plating on post-1983 cents. Every source I can find says pure copper. Yes, it's a bad choice, James. Have you LOOKED at any?!?!?! The plating is hyper-reactive on steroids, exactly what you'd expect from a pure copper plating. A tiny itsy bitsy hole through the plating and even slightly low pH water, and you've got a corrosion engine running. It's a tiny mini-battery.

Tridmn Posted November 17, 2020 Author Share Posted November 17, 2020 (edited) I'm not going to argue about the copper being taken off by some sort of chemical. I thought it was unique and wanted to show it. That's why I post on here; for answers to questions I cant answer. Sometimes I do post things that I can eventually find an answer to. Most here have done this for years, and are still doing it. That's why I ask first then start digging myself.

I used libraries to do research. Huge buildings, lots of books. Edited November 17, 2020 by VKurtB Modwriter 1 Link to comment Share on other sites More sharing options...
