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

    More than likely it is what they cal a MAD (misaligned die strike). What occurs is the hammer die is of center from the anvil die creating an off center strike on one of the coins surfaces. Since the collar forms around the anvil die, it is always the hammer die that appears to be off center, which in this case is the obverse.

      As BJ says, it's a very minor misaligned die error. So minor in fact that it falls within acceptable tolerances. These errors only count when part of the design is cut off.

        Hi Mike,

        That's the layman's language ->"design is cut-off" to be a major off-center (we novices, us 3NVTEs would love to request from forum respondents to include in their responses (if there are simple appropriate/applicable terms that could be added if there are technical explanations provided) should we erroneously ID'ed varieties or errors. If the offset was expressed in terms of "angle degrees", would be hard to measure nor remember.


        Thank you.

          An off center cent will affect both the obverse and reverse of the coin. As Mike mentioned, there are cases where the obverse die is so misaligned with the reverse die, that some of the outer design elements are 'cut-off', or missing while the reverse die is still well centered.
          So...in a nut-shell, should you find a die where one side of the coin looks like an off center strike, but the other side is fully struck and centered, then you have a misaligned die. The severity is determined by how much of the die is not centered by the strike.
