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

    1955-D/S Jefferson Nickel & Not a 1969-S DDO Cent

    First, here is an image of a 1955-D/S Jefferson Nickel for you viewing pleasure. Both coins have been added to the Variety Resourse page at my website.

    Your comments are always welcomed.



    Here is an extream example of die bounce. Many people ask why aren't coins like this Doubled Dies. The flat shelves, and the doubled mint mark are always the first place to look! Doubled dies have split serifs; shelf doubling does not.

    That photo of the 69s cent is a good photo that shows one of the many forms of the not very valuable maching doubling. maybe some collectors can learn from it. I'm tinkering with a homemade lens I made for my old camera tonight and I'm adding a photo of a 1994 p mint quarter with the machine or what I call strike doubling. I'm mostly wanting to see how my photo looks like after it gets on the website. If you can see my photo look how far the letters in God were pushed over , the D is starting to overlap the O . I don't think very many people is collecting the mechanical doubling coins as of yet but we never know what folks may want in the future.I'm keeping the 1994 and a few 1996 ones that I have been finding with this extreme MD. It don't cost anything to keep them.
