That is a strong machine doubled/damaged devices example. I would like to see a closer shot of the date?

Closer picture of the date. It looks like Abe has 3 shirts on.  |

I have seen two 1992 Lincolns with MD similar to the one you have here. They may very well all be from the same unstable die giving similar yet different results. The example below belongs to Dave Kearns.  |

That coin does appear to be very close to the one I posted.

Would an MD misshape the letters so much though? I'm still new to this idea of MD vs. DD and recognizing them. It seems to me that the R in LIBERTY was reshaped by a secondary strike, yet Lincoln's face didn't double like his profile did... awaiting further knowledge dropping!

TheGoodGuys, Strike Doubling (aka Machine or Mechanical Doubling) has its origins in the original characters/designs in that it is smashed down from those elements. Thus, for there to be a flattened down area to start with, you need a source, i.e., the original design elements. (I know I'm being redundant.) This form of Strike Doubling is the most common. It will reduce the diameter of the original character.   |

Koinpros, so this would be opposed to Double Die where there will be 2 distinct and sharp numbers or letters? Strike Doubling (MD) merely puts another layer or line into existing characters making them appear thinner. In your second image I noticed that Lincoln's face, without the outermost lines, becomes misshapen and not normal looking. Interesting, I'm sure many of the "questionable" coins I have in my collection could be ruled out now... |

Wow,that is extreme MD-pretty cool...good guys,picture the hammer and anvil dies closing down on the planchet then shifting or shaking a bit causing one die to drag the original design/characters get this flattened metal effect giving it a doubling effect and thus taking some metal from the original design with it reducing the size of the original-I may of made it more confusing hope I didn't-just trying to help you visualize it...

GoodGuy, This should help a lot. The fist image is of a genuine 1969-S Doubled Die cent (the Tremonti Specimen).  The next image (below) is of another genuine 1969-S Doubled Die but with heavy Strike Doubling (aka MD) on the 96 of date and S Mintmark (the Bowman specimen). Notice how the hub doubling (doubled die doubling) the 96 and S on the Bowman specimen has been narrowed by the Strike Doubling. It's kind of like paving a street and then making curbs a week later. If a car drives the up in the curb just half-way and drives its length, the width of the curb will now be half of what it started out to be.  Edited by koinpro
