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

    1956 10C PR DDO-001

    Hello, you wonderful people! I’ve got here what I suspect to be a DDO-001 1956 10C proof. I’ve compared it against the CONECA images and Variety Vista and tried my best to take good images for comparison, but I wanted to know what you all think!

    Have a lovely weekend all!

    In my opinion, although the general area is correct, the actual location is not. What I mean is, on variety vista, look at the exact location where the doubling occurs. Does it match up exactly to your coin in hand ?

    Proof coins typically receive more than one strike to bring out the best quality for the collector. This method can create an illusion that is collectible. Some times it ism but most times it is not.

    The working dies when they were created might have received more than one impression onto the dies so they could show the complete coin design. If the mint workers inspected the die after each impression, and the die placement back into the press was just a tad off, a doubled die may have been created.

    These working dies are made of steel. So when an image is impressed onto the working dies, the location of the doubling will not move. The doubling on tbe attributors website, and what you see on your coin should look nearly exact. The doubling might change in appearance a bit as the die gets older through use, but generally, the location remains the same.

    Happy hunting.
