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

  • Did they used to fix DD's by hand 1970 s

    I was watching one of those videos on how the minting process works and I want to say during the time that they were talking about repunching mint marks by hand they also mentioned that they used to fix doubled dies by hand also.
    Did this used to be a thing?
    The reason I ask is there's a lot of similarities between my coin and FS-101 (029) on variety Vista.

        I see no Doubled Die here, Die Deterioration, thinning of the devices, and Machine Doubling, I just don't see any similarities to the FS-101.
        The floating Roof is caused by the over polishing of the die at some point, could they try to blend a Doubled Die off of a Die? IDK lets see what the others say.

          In my opinion, I highly doubt they would blend out a doubled die. Those working dies have the impressions sunk into the die themselves, so they are raised on the coin. in order to remove a doubled die, they would have to painstakingly fill each area by hand taking quite a large amount of people-hours. It would make more sense to simply remove the die and replace it.

          They DO blend out die clashes, but with all that die abrasion, the flat fields of the coin looks like a Bear scratched it up.

          As for the OP's coin, I agree with DT, its simply some sort of worthless doubling. There is no added thickness on the devices nor any well recognized split serifs or cookie cutter style lines.

          These working dies are metal. The working dies that had more than one noticeable impression are made of steel, so what the attributor shows for reference points should match what you should see on yours. not much room for wiggle room.
