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

  • New to Errors/Varieties Have a question

    Good evening, everyone, I’ve been collecting coins for a long time, however I’m new to errors and varieties. I’m not yet a member..yet. I have a coin that has me a bit confused. It is a 1993 P LMC with what appears to be doubled obverse, in the hair, front of face and neck. I’ve gone back and forth in my mind between Machine Doubling and DD, I just don’t have the knowledge to determine which. There appears to be 3 separate impressions to the right of the face and neck, as well as file marks. I would appreciate any assistance you can give. Thank you in advance

      In my opinion it could be:

      Or

        Thanks for your opinions. The part that has me stumped is the file marks on the field SW-NE are also present in the area in question, the front of bust from hair to neck. Which (correct me if wrong) would indicate some type of die repair or reworking, that isn’t present on the actual bust. Again thanks .

          thanks for the pics. just wanted to make sure 100% i wasn't missing a light double-struck or someone just outlining the profile with a nail or something. i've seen just about everything at this point as i am sure a few others on here have.

          i concur with gary as he knows what he is doing and did better with the pics than i did. some form of mechanical doubling.

              In my opinion, those are die scratches from maintenance of the die. Some type of abrasive tool was used to clear out the gunk and make the die last a bit longer. That is pretty common to see on the working dies. If they are risen on the coin, it could be that it was done in the mint.

              90 percent of the time the die scratches are on the field only, but occasionally the happen on devices too. The Mint workers seem to avoid scrubbing anything sunk into or incused on the the working dies.

                I thought it looked as though a mint employee did a heavy file job. Thanks everyone, for the links also. Good information.
