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

  • 1971 half dollar question?

    While looking through my 1971 proof sets I noticed there were two varieties. A common as in 5 of my 7 sets with type As and 2 not so common type B. I’m Just using type A and B as distinctions between the two. I don’t know if there is any official type assigned. I’m looking for information, thoughts or comments. See attached photos.

    - The I in “IN” has rounded corners on the type A, but notched corners in type B,
    - The I in “LIBERTY” has rounded corners on the type A, but notched corners in type B,
    - THE leg of the R in ‘’LIBERTY” is even or lower than the hair which curls over it in the type A, however the leg of the R is higher that the hair in the B.

    In James Wiles The Kennedy Half Dollar Book, and the CONECA Master Listings of Die Varieties, your Type A is referred to as Obverse Die Variety 002 (ODV-002) and your Type B is referred to as Obverse Die Variety 003 (ODV-003). Some call them a weak R and strong R varieties. There is series doubling on the ODV-003.

      Thanks for the information. It was a new discovery for me, I'll add it to my data base as another thing to look for.

        As mentioned the Wiles E-books are good, along with the www.varietyvista.com website.

        NGC has a variety plus area at
        http://www.ngccoin.com/coin-varieties/

        PCGS has their varieties buried under the date tree of coin prices area;
        http://www.pcgs.com/prices/
        specifically;
        http://www.pcgs.com/prices/priceguid...dy+half+dollar

        For pcgs varieties, look to the far left column of the coin year, it should have a (+) sign that you can expand and see varieties.

        John Wexler has a side at www.doubleddie.com as well.

        Those are my quick-look references when I find die varieties and errors.

          My quick-look reference when it comes to die varieties, especially for Kennedy Half Dollars is the CONECA Master Listings of Die Varieties that James Wiles maintains on Variety Vista.
