    I found a 1981 no mm penny with doubling in "United States of America" on the back. Does it have any value? Can't find anything on it.
    I also have a 1982 no mm with doubling in " United States of America" and "e pluribus unum" is it of any value?

    I have pics of that 1981 penny with doubling on the back. Is it machine doubling? If not is it worth anything? I can't find anything on it anywhere.

    Machine Damage doubling with no added value.

    What is the difference between DDR and machine damage?

    A doubled die coin is a coin that is struck by a die that was doubled during the die making process.

    Machine damage (or MD) occurs when the coin is struck. After striking, the die may lightly tap the coin again, flattening part of the design and give the appearance of doubling.

    A little more detail.

    When dies are made, they are heated to soften them and then pressed into a Working Hub. This is called the Hubbing Process.

    Since a single press, at the time of higher relief coins, was not enough to bring out the details of the coin, a second hubbing was required which meant removing the die, heating it again then reinstalling it in the press. If the re-installed die was not lined up exactly OR if some distortion occurred due to the heating process, then a duplicate impression would get hubbed into the die being created. Hence, the term "doubled die" since the doubling occurs on the die itself.

    Doubled Die usually ALWAYS have rounded 2nd images.
    Machine Doubled coins almost ALWAYS have flat doubled images.

    Thank you very much. I have a better understanding of the double die now. Now I know what to look for instead of wasting my time wounding if i have something valuable or not.
