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

    1961 GW proof

    A combination of DDO and mechanical?

    Coin was in a roll, and had a tough ride at some point...lots of scratches (groan)

    The G looks like it's suffering from die deterioration doubling. The faint doubling around the B looks like a consquence of die movement between strikes. Proof coins are struck more than once.

        I totally agree with mike yes it looks like Die deterioration doubling, sorry eyesore . I do see possible notching on the G through , could be a doubled die plus Die deterioration doubling also both can coesist on a coin .Brad Coinart

          Proof Doubled Die's are hard to confirm. I know for sure in hand you can see more than a photo will show. but you can send off to get attributed or graded.
          I agree with Mike

            Don't feel too bad

            Hit an auction in the middle of a blizzard last year, and got a bunch of rolls at melt..I'd set the 61 GW off to the side meaning to get back to it, and just plain forgot too.

            One reason for the distraction was that there were 2 of these in the mix of Roos. There were also a half dozen gem Type B GW's

              Eyesore if I had in hand I could tell better what it is

              I no grader but photo's of the motto & date look like a winner.

                    It looks like to me but a TPG may say it is not.
