I found this last night. I need help figuring what's going on with the date and mint mark. Is this Machine Doubling or is something else going on?   SORRY ABOUT TAKING SO LOG GETTING THESE PICS UP Some was on my computer and messed wth my settings. Here they ar. I hope they are clear enough. The second pic shows apparent Machine Doubling in TY.    Edited by thingee

The date looks like doubling...the mint mark begs to be RPM; however, I dont see it listed in any RPM reports, most of which indicate a West repunch.

that is a nice 1969 in which the 9 shows some doubling in it but I agree with thingee it looks like the s is a RPM

Classic case of Mechanical Doubling. Notice that the mint mark and the date are smeared in the same direction |

Machine doubling. Since the doubling is on the date and the MM, I believe that means it has to be Machine Doubling, correct me if I am wrong. On this date, the MM was hand stamped on the die after it was hubbed, so it could not be doubled on both in the hubbing process. Jim |

Oh, and it would be very hard to be an RPM and have the exact same appearance and phase shift (south) as that on the date. Guess it could happen but these have the flat shelf look a a Machine Doubling to me. Jim |

Yeah I figured it was Machine Doubling, pretty sure it was on the mintmark, not so sure on the 9. But hoping for the best that I was mistaken. Thanks for helping out everyone.  |

Yeah...I'd say MD too because it looks to be a low-relief shear, and the MM is doubled too. I hope you find one someday....  |

What always amazes me about coins like this one is how MD seems to be selective. I agree that it is MD, but notice how it appears only on the 9 and MM? You can see a little on the 1 but none on the 6 or other 9. When you see stuff like that, it makes you shake your head and think..."how is that possible?"
Is there any other MD on the obverse?

ANY time you see identical doubling in the date and on the mintmark of coins produced before 1990 it is always Machine Doubling. This is actually a very classic no-brainer case of Machine Doubling. |

I would like to see the whole obverse. This is MD but I differ in that mint mark was added afterwards.

Homer, before 1990, mint marks were hand punched into the die after it was hubbed. This means that any doubling conveyed to the die in the hubbing process would not be on the MM as it was not there when the devises were applied to the die. It was added later.

Here is another. This one may be a bit more exagerated. sorry about being up-side down, it is "raw":  I have other photos of the obverse that show a lot of MD on the profile. They are available if desired.   I thought I would post them, after all. They may clarify some details. Dick Edited by livingdinasaur

Is that Yours Livingdinasuar? I like to think it's a DD but most think it's MD.

Anything done to the working die will be conveyed to the planchet. MD is the displacement of metal in any direction, due to the movement in the retraction of the hammer, and the feeder arm inserting the blank into the collar for the next strike. It usually is referred to as "ejection doubling, MD shelf doubling, etc" It always, or most always will affect both the date and MM as a unit, die to physical location, See the profile photos, (if presented). This is clearly shown.
