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

    Hub doubling state quarter

    misread information from another group - this is not a form of hub doubling and not valuable. Let the hunt continue.

    As far as the doubled die, the 2006 Colorado has only one doubled die obverse, and that is associated with Washington's earlobe...

    In my opinion, what you are seeing on the L is known affectionately as worthless doubling. Worthless doubling is almost always lower and shelf or step like.

    With the newer one squeeze technology and all the pressure they use on those working dies - its a recipe for a wreck. Add in the fact that if devices are incused, metals do slip and move. I do not know of any United States Mint produced doubled dies that have been documented as doubled dies that are incused.
