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

  • 1977-D Strike Through?

    I found this Lincoln cent in a bank roll the other night. It was determined on another site that the "RPM" was most likely MD. That is probably correct, but I would still like another opinion.
    The incuse duckbill 3 still has me baffled. It is a dead-ringer for a duck-bill 3 from the 1983 ilk. It was suggested that two coins were pushed together with enough force to leave the incuse 3. I find it hard to imagine that enough force could be exerted to do this and not damage the coin in any other way. I am open to suggestions.

    One way to try to determine whether it is PMD or not is to think hmm... is there any way this could have happened at the mint? I don't really think so.

      I agree. I also don't see anyway it could have happened outside the mint either. Definitely not a vise job. I've seen many dozens of those after looking at hundreds of thousands of pennies. Possibly someone counter stamped? With a reverse 3 stamp? Even less likely. It will go into the "who knows" bin with the 5 or 6 others that no one really has a plausible explanation for.
