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

  • Help Needed with this 1971-S Business Strike IKE

    I've come across this Eisenhower that I'd like some opinions on. Yes it has evidence of machine doubling but I'd like the viewers to not focus on that as much as the other "strike anomolies" of the coin.

    In this picture, there appears to be a V in the upper lip which looks like the area where the two lips come together indicating perhaps remnants of an initial strike?

    This picture looks like the R was struck below a "first" R .

    This picture shows the designers initials. I've seen strike/ejection doubling on IKEs with some frequency but never involving the initials which this picture clearly shows as doubled.

    Below is a portion of the motto which appears to be one of the many IKE DDO coins.

    On the profile of the coin:

    I only see machine doubling. The edge of the design shows the expected marginal shelving while the interior of the design shows more rounded doubling.

      What would account for the R Mike?

        The R also shows machine doubling. It displays marginal shelving.

          Ok, let me get a bit more specific.

          I have seen machine doubling and can spot it rather efficiently but I've never seen machine doubling that leaves a gap such as what is displayed below:

          The two upper arrows point to what I believe are the remnants of an R from a previous strike which accounts for the gap between the two devices.

          These next photo's show the rim near the R and the exact opposite rim under the first 1 in the date.


          To me, its relatively easy to see a certain offset where the rim near the R is Sharp and almost railroaded while the rim near the one is rounded. The sharp edge flows eliptically around the rim of the coin folding over at around the K3 and K9 positions.

          Next, I'll show the hair under the E and R in side by side photo's of a normal IKE and this particular IKE.



          Again, I can understand rounded machine ejection doubling (kinda) but I cannot understand machine ejection doubling of uncused areas such as indicated above.

          Lastly, consider this mintmark comparison.


          An enlargement of the MM showing where the upper loop is completely split.

          Personally, I think an initial strike was to the north and a second strike was offset (misaligned dies) to the south.

            Ah, thank you for clarifying. It does appear that the coin was struck twice and that there was slight movement between two of the strikes. I think you've got a combination of conventional machine doubling and a slight misalignment between the first and second strike.

            It's probably hard to tell which of the rounded interior doubling is due to machine doubling and which is due to the slight misalignment between strikes.

              Thanks Mike!

              This coin must be viewed in hand to really get a feel for whats going on with it.

                I did send this coin to Mike Diamond who returned it with the following:

                "It does show clear evidence of a close double strike on the obverse. The best evidence is 1) a totally separate top of the "R" of LIBERTY, 2) a flattened S-mintmark above the raised mintmark, and 3) the rim line that lies inside the definitive design rim.

                The rest of the doubling appears to be machine doubling. That would include the doubling on Ike's face, the date, and IN GOD WE TRUST.

                It seems that the double strike came first, with the second strike slightly south of the first one. The die bounced after the second strike, moved north, and landed lightly a third time, creating the machine doubling."

                I then sent it to PCGS with the following results:

                The coin is heavily laden with die polish lines which does nothing for its appearance! For now, I'll keep it as a reminder of what can be found out there as this had all the earmarks of simply another machine doubled IKE.

                I've since come to learn that several collectors have found similar coins in 1972-S adn 1973-S.

                Did I say Thanks Mike?

                Thanks Mike, I appreciate your dedication and knowledge.
