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

  • 1968S Jefferson Proof Nickel DDO?

    I am looking at a very nice Butterscotch colored 1968S Jefferson Proof Nickel. I am seeing what appears to me to be possibly Class I CCW Doubling. I have narrowed it down to DDO-007, DDO-009, DDO-017, DDO-018 or possibly DDO-026. Or it could also be none of the above! Thoughts or comments?

    I just can't tell. Have you been able to find any markers at all? There are so many similar ones for the date and I am also having a hard time verifying if it is indeed a class 1 DDO to begin with. I will let a nickel person have at this one as I can not verify anything at this point.

      Hello Bob, Thanks for the input. I have gone through all the DDO on VV and through the process of elimination using die markers and mint mark similarities have narrowed it down to the ones I listed. I eliminated DDO-023 because it was CW. I can only find three anomalies. There is a rough patch on the cheek which looks like it is sunken in instead of raised. There are what appear to be a group of die scratches. Finally there is a small die chip. I don't see anything on the reverse. I have attached pics. Thanks again for the help.

        I tried to match it up with the 1968 S with with CCW rotation and do not see a match either. Is there any spread on the star or the designer's initials? I can't tell from the photos.

          My suspicion is that the coin has deceptive machine doubling - on proofs it is especially deceptive, but common. I do not see notching or splits.

            Hello N-6503, Thanks for the comments. I have attached pics of the star and the designers initials for your reference.

              Hello Jason, Thanks for the input. The only split I see is on the 'I' in IN. I have attached a pic of that.

                I am not convinced that is a split. We really should see notched corners in multiple places.
