    Color pictures would be helpful.

    Otherwise, it looks like a badly corroded cent.

    Post mint damage (PMD) The copper layer has been removed.

    Sorry, but it's not an error. The copper plating was chemically removed after it left the mint. It's not struck on an unplated planchet. Just some "Gee Mr. Wizard" fun with chemistry.

    Welcome to the forum @ChengHang1a.

    Spend it before it corrodes away. Without the copper coating the zinc will just react/rot away.

    Worth 1 cent and value decreasing.

    Also the use of B&W pics to hide or enhance features should not be done. The usual standard in focus color pics are preferred.

    I’m sorry for the picture misunderstanding. The pictures I took of the 1991 penny wasn’t altered any type of way. The pictures I posted here are the originals. No B&W filter was utilized. The colors seen here are the color of the penny. I’ve watched a video from BlueRidge on how to know the difference from an acid chemistry lab copper un-plating removal between a genuine mint error un-platted. With the chemical removal the quality/definition of the penny will diminish considerably. The genuine mint error in-platted penny will have all its features and define edges reverse and obverse. Plus the wordings on the penny is a odd Type of Double Die. Thank out for your response, but I’m not leaning towards it being chemically ruined. I can send the pics to anyone via email. The color of the penny and errors on the penny wasn’t enhanced or altered in any kind of way. I’m new to numismatic so I really need help on this one. It has to be more to the penny. It still has all the memorial building steps no wears on the year, Liberty, In God We Trust, United States Of America or One Cent all the define features are still there. Thanks

    What’s the weight, diameter, and please show an edge pic.

    Suspect it might be cast.

    No idea why one would take the time to cast a 1991 cent but science experiments do happen.

    Be careful what you believe on the YouTube videos. Many are filled with incorrect info and misinformation.

    The key characteristic in determining whether the cent was struck on an unplated planchet is the presence of mint luster. A coin that had the copper chemically removed after it left the mint will have a dull appearance. This information has been posted on numismatic forums by some of the foremost experts on error coins. There also appears to have some corrosion on both sides, which could also be caused be the chemicals. Your coin does not look like it left the mint in that condition. If you still believe the BlueRidge youtube guy is correct, then you can send your coin to PCGS or other TPG to have it authenticated. IMO, it will be a waste of money, but that‘s your choice

    It's not a "double" die nor is it an error coin.

    @loro1rojo: Thank you for your answer to the post. I’ve no idea what I have. I’m a beginner to coin collecting/numismatic. You’d said it’s neither “double die” or an error coin. If you will, can you Please let me know what it is I have. Any info is appreciated.

    My sincere apology’s for coming off /being complicated. Sorry, if I’d offended some with the little knowledge I have by replying back. I do it so I can get a better understanding.
    Thank you.
