As most of you know I am new to the forum. I have been trying to post pics/questions and now have a new camera that will hopefully produce a good quality picture.So here goes I have found a 2011 Jefferson nickel with doubling on reverse on the end on "monticello and cents" Not sure what to call it, thought I would bring it to the forum for comments. Thanks  Edited by Cindy Wood

ON the Monticello I think it is Machine Doubling, no I think it could be but I will let the experts speak. |

Please educate me.....what's the difference between Machine Doubling and true doubling? |

Interesting - can you get an isolated shot of the affected area? Not too close though. This may help in identifying which kind of doubling is at hand.

Agrippa - I think you posted a link or two to a write up but Wexler's site offers explanations on what is valuable doubling (DDO, DDR, RPM, etc) vs. worthless doubling. MD is suggested as being worthless doubling caused by slop in the equipment during the coining process (I'm sure Gary, Mike, Coop would be more precise in the explanation). |

Agh, that's right....notching and widened lettering versus slopes and such.
That is a nice pic!

Looks like "NTS" is also doubled in "CENTS". I guess I get confused when I think about the process of striking a coin. I don't understand how Machine Doubling could only happen to the inside portion of a coin, like this one, and not effect the whole coin? Or at least a greater portion? I gotta go do more research! :) |

MD in my opinion. The doubling is flat.

There also seems to be something going on with the date  |

I have such a hard time with this. It looks like a DDR to me because based on the picture it does not look flat and shelf like. Nice either way! |

I agree Deb - while it may be MD, I think that the MD seen on the more recent Jefferson nickels tends to be more extreme than examples from other denominations and genre. Cindy - thanks for the extra pics. Very cool looking no matter how this shakes out. I wouldn't have thought to examine a 2011 for this condition, but I just might going forward. If you are seeing something else going on with the date, it may suggest movement in the tooling when coining the planchet. Let's see what the big guns can tell us about the coin. Agrippa - I know what you mean regarding affected vs. unaffected area. From what I understand, the focal point may not be directly on center - it may be centered about another spot on the coin such as the date. The movement most noticeable occurs elsewhere on the coin, usually at the most extreme point. I think I read that this is why the 1995 date on the LMC DDO looks generally 'perfect' while the LIBERTY is noticeably doubled and the Motto less so as you rotate towards the date. On Cindy's coin, the affected areas on the obverse and reverse are in the same 'corner' of the coin (I think). This makes me think that the center of rotation is set off center to the coin. I'm theorizing here...so I may be way off base. |

I would hold on to that coin my self. If it IS actually MD then it would be a great example to have around to refer back to if you find a similar coin so you can make a comparison. Just an opinion.  |
