  • 1989 Lincoln Cent — Possible Machine Doubling? Seeking Help & Opinions

    Hello everyone! I’m fairly new to error collecting and still learning how to distinguish between true doubled dies and machine doubling. I recently came across a 1989 Lincoln Cent that shows what appears to be doubling on Lincoln’s ear and some pretty extreme doubling on the letters in “AMERICA” on the reverse.

    I’ve reviewed several error-reference guides but haven’t found any mention of a known doubled die for this year that matches what I’m seeing, which leads me to believe it might be machine doubling. However, I’d really appreciate a second (or third!) opinion from more experienced collectors. I’ll attach several close-up photos so you can see the details.

    Thank you so much for any help and feedback you can provide.

    This was posted twice. One they will probably let be on this forum, the other they may delete.

    In my opinion it's pretty rare for a cent to have both an obversecand reverse with a doubled die. It happens, but it is scarce.

    The AMERICA looks like machine (worthless) doubling or, if you see string around the letters, the strike may have been too strong and the working die broke though the thin copper plating which exposes the zinc core. The bluish zinc can leal out, staining tne surface of the coin.

    If you visit websites like

    It's important to read the description where the doubling actually occurs. The
    Description and appropriate photos will show you where the doubling is. These working dies are made of steel, so when multiple impressions are sunk into the working die, that doubling does not move. What is sunk into the die, is raised on the coin when the dies squeeze theblank into a coin.

      Thank you so much for your insights and reply! I’d like to apologize for the double post; I first posted in the general forum before realizing it was the wrong place. I’m still learning how to navigate the site and will see if I can remove the other post today. I appreciate all the guidance on where and how doubling typically occurs—I have a lot to learn.

      Regarding the coin’s strike, it seems very sharp, clear, and deep overall, especially on the reverse (if I’m using the right term). That lines up with your assessment that the working die may have broken through the thin copper plating, exposing the bluish zinc core. I’ve also noticed a fair amount of bluish staining in several spots on the reverse.

      I’m curious: what are your thoughts on Lincoln’s earlobe on the obverse?

        All I can say is its best to use the reference sites to see which years/mint marks have the ear, eye, column doubled dies. IF there are not any listed for that year then it is probably something else.
