CONECA (pronounced: CŌ´NECA) is a national numismatic organization devoted to the education of error and variety coin collectors. CONECA focuses on many error and variety specialties, including doubled dies, Repunched mintmarks, multiple errors, clips, double strikes, off-metals and off-centers—just to name a few. In addition to its website, CONECA publishes an educational journal, The Errorscope, which is printed and mailed to members bimonthly. CONECA offers a lending library, examination, listing and attribution services; it holds annual meetings at major conventions (referred to as Errorama) around the country.

CONECA was formed through a merger of CONE and NECA in early 1983. To learn more about the fascinating HISTORY OF THE ERROR HOBBY and THE HISTORY OF CONECA, we encourage you to visit us our main site Here

    Is this a RPM on a 1946 D Jefferson Nickel?

    In my opinion, i am not a big nickel fan but, i believe this to be some sort of mechanical damage. The vertical crossbar is super thin and the eastern (right) side where the curve of the primary D is completely flat.

    Looking at the coin, the area by the verical bar is the the left and the area near the curve of the D is to the right.

    What i do in situations like this is to get some thin paper, tracing paper is best. On the screen, carefully Outline the stronger D in pencil. Then, slide that traced D and see if it lines up on the weaker D.

    eaxtellcoin is an outstanding reference for nickels. If he has some free time, he might come in here and offer is opinion.

    I personal do not see a match on variety vista:


    I did not check

    or
    Die varieties such as doubled dies, Repunched mint marks (RPMs), Over Mint Marks (OMMs), Repunched Dates, Overdates, coin design varieties, as well as regular coins and error coins.


    Each working die that had an rpm hammered into it the all had a slightly different location. You can look over the different mint marks on documented RPMs and see the different mint mark locations. People can do overlays to confirm or debunk rpms against known, documented examples.

      This to me looks more like MD also. Sorry. The shelf is there to the West. Some of these are very convincing because the extra movement is only on the mintmark. They call this Localized MD.

        I think you correct. I did not realize the doubling could be that limited. Thank you

          Think of it this way. The mint mark is hand punched into the working die. Its an extremely small hole. When the working dies squeeze that planchet into a coin, that area of the mint mark is hopefully filled with some of the coin's metal. After the coin has been squuezed, it has to leave the working dies. If its not pulled up/ejected exactly like it was put in, things can get damaged. I also believe that the depth of the mint mark has something to do with all of this. If the machine, working die or coin/planchet moves just a tad as the coin is ejected from the working dies, it probably can damage the coin.
