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

  • 1946d cent

    I recently discovered this doubling on my 1946d cent on the e pluribus Unum. Any help would be appreciated. This is my first post ever and hope the pictures are legible and worthy.

    To me, the photos are small, and I can't personally see them very well.
    The photos are good, but maybe a tad small.

    I am currently writing a post so downloading these and looking them over is not an ideal time for me.

    What I suggest to do is go visit

    To make it easier, I copied the URL out here for the 46D DDR's 1946-D DDRs (varietyvista.com)

    James Wiles categorized a lot of doubled die reverse's (DDR's) and you might be able to match one of them up to your coin.
    Be careful though, there is another condition known as "strike doubling", "Shelf doubling" or "mechanical doubling" that can look like a doubled die, but it is not. All those three mentioned above is damage done to the coin when the die does not clear the coin properly.

        Those extra photos helped a lot. I was able to definitively identify the doubling you see as mechanical. There is no premium for this common striking error.

          Great, thanks so. I have Bob. I knew there was something but wasn’t sure. Some older doubled die coins appear as MD, so I was checking.

            You are correct in that some forms of worthless doubling can mimic hub doubling and vice versa. However, close scrutiny and knowing what can happen in the hubbing/striking processes can help immensely. Knowing the specifics of each class of doubling can help answer questions as well. I guess it doesn't hurt to have over 50 years of experience either, but that certainly doesn't mean I am 100% right all the time. It is a learning process your entire life.

              Yes, thanks again for the help. It’s kind of overwhelming, but at least I found a hobby being retired. Too bad I didn’t discover it sooner
