So, I just found what looks like a possible RPM on a 1954 D Roosevelt dime. But when I looked on Variety Vista, I couldn't find anything to match it. does that mean that it is not an RPM? Is there any other explanation for what could cause the MM to look like this?   |

It does not look like a RPM to me. MD or damage. John1  |

Thank you both for your replies. I have passed up a few coins like this in the past, I just wanted to be sure that I wasn't passing up something significant. I had always assumed that if it was caused by MD, then I would see the same doubling effect on other letters or features surrounding the MM. And the way that the curve on the front of the D looked to be doubled just seemed too precise for PMD. But now I can put my doubts to rest and move on. Thanks again for your help! |

Looks like Machine Doubling, since the mint mark was reduced in size and it has a shelf like appearance to it. Errers and Varietys.

After looking more closely at my own images, I can now see the "shelf like appearance" of the doubling. Before when I was first looking at it, it seemed to me that the extension of the MM appeared to be rounded. But after seeing the example pics posted by Coop, my perspective on that has changed. Thank you for your input.
My only question now is, how is it that the doubling is so pronounced on the MM, but the surrounding features seem unaffected by MD? Not that I am doubting anybody's word here. I am just curious, and hope to learn more about how MD can occur. I have seem many other cases of obvious MD on dimes and other coins. But in those cases there were always multiple features in one area that all shared similar MD details that gradually become less noticable as you move away from the central area.

Keep in mind the mint marks are hand punched into the die. The other devices are all the same size in height. The mint mark can be taller and take a glancing blow quicker or die movement after the strike. (which I feel it was caused by as the curve is shown you coin. Coin contact would not affect the mint mark that way, but a high bounce and swing after the strike alters that area.
