CONECA (pronounced: CŌ´NECA) was formed through a merger of CONE and NECA in early 1983 and 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 to name a few. In addition to its websites, CONECA publishes an educational bi-monthly journal, The Errorscope, sent to members.
