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

    John Adams Dollar

    I am looking for some help with the edge lettering on the John Adams Dollars. I recently looked at 300 dollars and found 21 of the coins with edge lettering that is shaped like a "u" with the edges striaght and the bottom flat and what looks like the outline of the letter at the bottom. All the other coins have edge lettering that is shaped like a "v". The difference between the two is very easy to identify. Has anyone noticed this? I am also looking for ideas on a possible cause.

    I assume you are referring to the vertical cross-sectional profile of the individual letters. At least two lettering styles are in use.
