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

    I can't seem to find attribution number maybe there's just too much damage to the words? But I can't find anything to match the date and mint mark either

    Greetings, this is a classic example of "Push Doubling" and is why there is no listing for your example here.

      Okay but push doubling still removes material from the area. There is no material removed and the doubling area especially noticeable on the 7 is wider and rounded corners then the original seven, and at that the doubling that is there looks bubbled not flat... And the lower part of the mint mark was not doubled

        Lets think about this in a different way, in a process way that is. After the Die that struck this coin had completed its process of creation, witch during the Hubbing, the Mistake or Error as it were "would" have been born on this Die, that would have eventually transferred that Doubling Error to all the coins struck by this Die like a finger print. Now letting that go for just for now, lets talk about the Mint Mark. All Mint marks were hand struck or stamped, depending on who you talk to, and that practice ended in 1989, so 1990 and beyond the mint mark was added to the die along with the design. So with the mint mark added "after the Obverse design was created on the Die we have to ask the hard question of why does the mint mark share the same Doubling as the date ?
        There is a simple fact here that Doubling on this coin involves both the date and the Mint mark in the same direction and degree more or less, there is always the possibility of an RPM on this MM but I had already checked before my first statement was drawn too you and none listed matched. http://www.varietyvista.com/02b%20LC...Ms%201970S.htm
        Now as far as the shape of roundness you pointed out I always take in consideration of Circulation wear as well. look I am in no way trying to shatter your hopes for a nice find , but just trying to shed light on a reality of physical facts struck in metal. 1970..2023...that is 54 years ish of 100`s of 1,000 of eyeballs looking through coin rolls ,Mint bags and so on with Experts examining coins with each new year, and nobody found a 1970 S DDO with this fingerprint of a Doubled Die Date with a NE RPM, and if the "S" was as well an RPM with a Doubled Die date this coin would have been listed as a 1970S Large date Dual Variety, but even as you stated "I can't seem to find attribution number" must tell you and all reading this post that, if it doesn't match any listed examples, then it`s something else. I am sorry but I do real care about helping others understand about coins as much as I honestly can here is the VV listings.

        And as well this is a very interesting source

          You're not shattering any thing for me by giving me your honest professional opinion. I am actually trying to learn and understand how this stuff works.
          What about this one. 1970-S 1˘ WDDO-054 wexler's

            I’m at work right now, but that’s not a problem for I can look again at Wexler’s . A lot to look up there so please give me an actual link to that page so on my lunch break I can more easily get there being on my phone is kinda clunky.
            I’m glad we can keep talking about your coin, because the more we go through this stuff the more we keep the education going.

                Mike I just seen your comment, and seeing that I have made a mistake in my comment
                this is a LARGE date . Thanks for bringing this up, and is a good reason not to be commenting on such complex
                topics after a 13 hour shift so late at night, my humble apologies .

                  Fresh find As I promised, I looked again scrolling slowly along the the Double Trail and found as before none along the way. At WDDO-054 I find nothing resembling your coins date and MM, Doubling shows below the bottom right and below the top left of the zero in the date. Doubling also shows below the top of the seven in the date.

                  So we have done all we can here to dismiss Machine /Mechanical Doubling push Doubling etc etc. without success, "in all other respects" we failed but we learned that ,once again "if we can not find a perfect match to a know listed variety(especially from this long ago) it is something else. Never forget that the MM from 1989 and before being hand punched means they were done after the Die has been imprinted with the design, and characteristics that was passed along to your coin, and if a mistake/error accrued and a DD was born, the MM was not included. So for the sake of a wonderful example of a Mechanical Doubling of some sorts on this coin I personally would give it a dip in 100% Acetone, put it in a PVC free flip 2x2 of course and sleeve it for use as a teaching tool you own.
                  I hope this helps in some way at least, and I do know how you feel trust me I and many collectors of the age has felt these feeling of high and low when looking through the loupe
                  now we can move on to your next coin

                    I got another question for you guys have they ever tried to fix doubled dies for some reason I'm thinking that I heard that before...
                    The reason I ask is on the reverse is almost an exact match to the rarest of the 1970 s or most sought after anyway , 1970-S DDO-001, 1-O-I-CW
                    From the floating roof to all of e pluribus unum. And more
                    I think I want to start a new thread with this question and put pictures on there

                        Why did you post a different coin and as well year on this thread? Please start your own thread and topic or thing`s will become confused and disjointed.
