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

    1976 bicentennial quarter RPM?

    Not sure if this would be considered an RPM. Maybe you guys could help me determine if it is or if you've seen this before. KIMG0188.JPG KIMG0187.JPG KIMG0188.JPG

    It looks like die degradation where a metal particles filled in the center. I've seen a lot this especially quarter and nickel roll hunting.

      Thanks coindog ! I've seen the mint filled in on allot of old quarters too but don't see that definite line at the top very often. Thank you for the confirmation!
