    This coin boggles my mind I wonder why it has a more reddish color to it as from other grease strike strikes I’ve encountered on shields.
    It must’ve been struck very sharp and strong bc the rim is super shiny and considerable thicker than that of an uncirculated shield. (You’ll notice in the side by side image)

    It appears to be a grease error, but I believe the coin has been cleaned. It may be surprising for such a young penny, but often a more reddish color is the result of a cleaned coin. If it's an uncleaned grease error, it could be worth all kinds of money!

    Okay what I thought about the grease.
    I don’t see this being a cleaned coin at all despite the color characteristics don’t fall in line with it being cleaned by something.

    looks like it was coated in pepto bismol or calamine lotion or something. does it scrape off?

    2023 struck on grease, I doubt. The emmulsion for those horizontal presses is liquid base on glicerine. I will go more with strike adjustment after Hammer die change.

    when they change the dies today, they change all full part and start to strike. the adjustments are perform trough ABI+ control.

    My oppinion. I will look for the Mint link for the new era coins striking.

    PS: the cooling emmulsive solute will solidify at 340 to 380 C deg.

    See a Physician to consider if you have a mineral deficiency/onychomycosis/metal poisoning/matrix injury/chemical allergy-acetone family.

    Other than that, I got nothin', except maybe the struck thru grease thing...but if you are happy I am happy.

    Nothings coated on it at all.
    The lighter areas like on the reverse that are slight dings and such in the coin

    Take a cent and rub some catsup on it and compare. Looks like an acid etch.

    I just found one almost identical to yours. Mine was a Philly mint 2023. Mine also had a red (or I would describe as lacking its shine or luster) color and you could see the "brush lines" on both sides. Only the obverse had missing or weak struck lettering. Hope this helps.

    Send me an email with images of this coin the best u can take. I know it’ll be tough as when I photographed it it doesn’t look how does irl. Much better in hand for sure.
    how my mind works I look at things differently and interrupt them different so I can def say it hasn’t been cleaned.
    It could just be for whatever this date for being struck thru heavy grease this is what it looks like without a clear explanation.
    Or if u have Facebook search Matthew Vallee messenge me

    Looks cleaned to death. But wouldn't that scrape off the thin copper coating?

    My thoughts? . . . The planchet was not annealed and subsequently washed before strike.

    The nearly complete preservation of the mill lines on both sides of the coin, the squarish rims, the softer design details, the complete absence of cartwheel luster and the dull look has me thinkingthe above.

    Striking a properly annealed planchet should move far more metal than we see here. Moreover, the fully upset edge of the rim should be at least partially rounded by the strike, but appears not to have been, presumably because of higher than normal hardness.

    Moreover, the mill roller striations should have been completely obliterated by flow lines. A harder planchet (from bypassing the annealing process) inhibits those by-products of the striking process.

    Flowing metal produces luster, and we see none here. The absence of cartwheel luster would at least partially account for the extremely dull look of this coin.

    While the coin is notably lifeless, I do not believe it was cleaned. Normally, after annealing and quenching, planchets get washed and burnished to remove oxides and brighten them prior to striking.

    I believe this planchet went directly from blanking to the coining press.

    Do they even bother to anneal the copper plated zinc planchets? I didn't think Zinc work-hardens to an extent this was necessary...
