Roll searching and found this.

That is almost certainly an ordinary cent from which the brass plating has been removed via environmental damage.

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.

Is it really? I thought the plating was pure copper. No? Do you have a source for the brass plating? The Mint says "copper".

The mint surely wouldn't use "pure copper" as plating - that would be an exceptionally poor choice.

[1917]

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?

Hey, why not? Mexico surely did.

Weight of 85 and weight of 43 steel.

Show weight

[Tridmn]

Pic is too large, but weight of 85 is 2.45g.

I believe you are correct. The loss of the exterior copper plating exposes the inner zinc-copper alloy core to environmental erosion.

I was merely wanting to share weights. I knew the copper plating would take weight off, that's why I posted them; so there would be no confusion.

As does the Red Book and Coin World Almanac.

Listen To DW. NOBODY ELSE.😎☘ 

[VKurtB]

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.

Amen. Being on NGC’s payroll does not make one immune from having an oopsie.

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.

That’s an okay system. I entered the field several decades before the Internet existed. I used libraries to do research. Huge buildings, lots of books.
