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

    1994 -P 1c STRONG DDO & DDR but with missing elements

    Hi ALL!

    Here's one of my finds. Hope I identifiedthe errors correctly.

    - Does the Mint use automated polisher?
    - Don't they inspect after polishing? Or after the fix (if broken)?
    Or do they fix such mfg glitches?
    - How many would have they minted before inspection/finding out the
    boo-boo of their work?
    - Same question for contaminated die.

    Just to get a feel of our low tech (or is there more advanced than the US Mint plants) minting process.


    Thanks,
    J

    The coin was struck through a lubricant coating, possibly grease or oil. Very common.

      Thanks Mike!

      I now have distinction...

      - Just want to add that unusual attribute to the strong DDO & DDR
      anomalies of this coin.

      Thanks,
      J
