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

    1922 S Peace dollar DDO/VAM?

    I thought I was getting better at recognizing worthless doubling but I can not tell on this one. The fact that nearly everything has double or shadowing is confusing me. Anyone have insight here PICA0014.jpg PICA0015.jpg PICA0023.jpg PICA0013.jpg PICA0022.jpg PICA0018.jpg PICA0017.jpg PICA0016.jpg

    In my opinion, Worthless doubling almost always appears lower that the highest area on the coin. Another way to look at it is, if you raised that area up, does it look like a normal letter or number again?

    Worthless doubling typically shows:
    • Thinner letters, numbers or other devices.
    • They appear to show step like areas, one area lower than the other.

    Doubled dies typically show :
    • More than one impression on those steel working dies.
    • The doubling may make letters, numbers and other devices thicker.
    • The area showing doubling should be real close to the same height.
    • When the working hub presses the impressions on to the working die. It's with the same pressure, so when looking at the coin it should be extremely close to the same height.
    • Doubled dies may be slightly off axis, meaning that one impression may be a little off to the north, south, east or west. Depending on the severity of the "spread", one may see split serifs or notches on the tips of letters, numbers or other devices such as hair, eyes or feathers or more.
    • If you take a large coin or medal, take some playdoh and roll it out. Gently press that one coin side into the Playdoh. It should be sunk into the play to about 25% or more of the thickess of the coin.
    • Carefully attempt to remove the coin from the Playdoh.
    • You should have a half decent impression in front of you. Leaving this alone, take the same Playdoh with the impression, and try to place the coin back in exactly as it was.
    • Make sure to use the same amount of pressure.
    • Again, remove the coin and closely examine that Playdoh.
    • More than likely you just created a doubled die in Playdoh.
    • This is an example of how it might have happened at the US Mint with the tools and materials they use to create working dies.
    Happy hunting.
