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

    It could be one of three things.

    It could be a die chip, die cracked die or t de die gouge. If its dug into the die, it becomes raised on the coin.

    It could be a trapped gas bubble. They anneal or warm the planchets (coin blanks) up prior to them being struck into coins. It makes the meta little softer and the working dies last a little longer that way. If the planchet gets too hot, gas bubbles can form under the really thin copper layer.

    Most seasoned collectors would leave these types of issues alone in respect to collectability. They were widely available.

    Some of the definitions can be found at error-ref.com under the completed entries section.

    My guess is a gas bubble. They are problematic with zic coin s
