Hello Newly active in the community. I was wondering if I could get some help from the verterand. I have a 1971 Kennedy half that I was viewing and am not sure if it is a DDO or not. I have attached a couple zoomed pics that hopefully are good enought to be able to get some opinions. Thanks   *** Moved by Staff to a more appropriate forum. *** |

 ya'all to the family! No, that's MD, Machine Doubling caused by a slight bounce when struck. The true doubled dies are quit distinct. I'd post pix, but on tablet now, sorry. If Coop comes by, I'm sure he will, he's the goto guru.  |

Crazyb0 I was thinking it was MD too before I read your reply. (I'm not stealing your opinion)  |

I'll be the contrarian and say that looks more like Die Deterioration Doubling to me. In the coins that I've seen in hand, MD creates shelf doubling with a more distinct border between the affected area and the field. If you can't find any good pictures of that, I can go look for an example of MD text on a JFK half I have around here. This "soggy" looking border is what I see more in DDD. The die flow lines in the field also make me lean towards Die Deterioration Doubling. [edit: I wanted to edit to note my agreement that it's not a doubled die. Also to show Brian that there is an edit button to add to your previous comments.] Edited by Druu

The main thing here is that it is not a doubled die coin. |

If based on the "IN G" doubling seems to face to the outside towards the rim. Die Deterioration is my goto, unless there is more to the coin. Thanks, Doug. Edited by Halo1st

I haven't had any experience with either DD or MD, so appreciate all the help.
I have four other coins, same year, that look exactly the same.
Thought I might have gotten lucky.

THC, if you don't mind the intrusion, I'll post a picture of machine doubled text and Die Deterioration doubled text.   The doubling on UNITED is MD. You'll notice that it's shelf-like and there's a crisp edge to it. In an MD vs true doubled die comparison, MD causes the features or lettering to appear smaller, whereas a true doubled die creates a fatter appearance. The doubling on GOD is Die Deterioration Doubling. Notice that the outlines of the letters are fuzzy. If you find one coin with Die Deterioration Doubling, you may find more, since all coins struck with that die from that point on will have similar or worse deterioration. I believe I have two half dollars of the same year and mint that exhibit the doubling on GOD. Edited by Druu

It is machine damage after the strike. Note the differences on the image below:  Note how the MD example on the left is reduced in size from a normal die. That die movement after the strike altered the device on your coin. The example of the right is a doubled die. Note how the devices are enlarged because the die was doubled? |
