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

    1978-S cent

    I am new to this site and I need advice on what to do.
    I found a 1978-S cent with a filled mint mark, and much doubling on Liberty,and the motto and the date. I thought that proof coins did not have such problems. being new to collecting I have read a lot, but cannot locate anything on this coin. What is recomended
    Thank you

    There are many forms of doubling. The mintmark probably has a die chip. Minor errors can be found on proof coins. A photo or two would help.
