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

    In my opinion, we would need a better photo of the date and full mint mark to determine if its a RPM.

    If you want, you can research the possibilities over at:

    Http://varietyvista.com

    Its important to scrutinize the position of the mint mark. Every working die had its mint mark hammered into the die by hand, so the position of mint marks can vary a bit.

    As for doubled die listings, its vital to read the description to find out where the doubling was documented.

    I also have some helpful posts in my signature block below. Including one about taking photos with a cell phone.

      If you are referring to the 6 then that appears to be die deterioration and the 9 looks like PSD. Cannot see bottom half of mintmark so cannot make a determination on the RPM.

        In my opinion, It would be great if you crop out all that unnecessary background. It will save space and focus on the coin vice all that background. Most photo editors of any type allow you to draw a box around the area you want to keep and the crop tool may look like a bent square icon.

        This is not DDO 002 on varietyvista.com . I have quite a few of DDOs 001 and 002.

          One last thing. Back in the day, the working dies are made first, without any mint marks. Later on when the working dies were about to make coins, the mint (Denver in this case) needed to add the mintmark to the working dies. They used to hand punch them into the working die using a mint mark punch and a mallet.

          So, you have two things here, one is a working die which is made seperately from the mint mark. And with that being said, the mint mark and the working die would not have the same areas of doubling, since they were done at different times.

          So the logical side tells me its more than likely is strike damage (worthless doubling) related. From 1989 and prior years, there are very few instances where there is a doubled die and a repunched mint mark on the same working die.

          Again, the description of the listing should give this information.
