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

    I do agree I was stuck looking at the 0 and looking closely at it it doesn't seem to have the the small o in it nor does the six . But I don't think it is a proof strike , I think it has a proof like appearance especially the reverse it is very sharp and beautiful details .

    I do appreciate your helpful input and now know that it is not an overdate .

    Thanks again

    In my opinion, it is localized machine doubling (worthless) of some sort.
    The area appears to be lower and shelf like.
    The letter appears to be thinner.
    If that letter was brought up to the same height, it would look like a normal letter.

    Doubled dies typically are a bit wider than normal
    Doubled dies typically have the affected area close to the same height.
    Doubled dies may exhibit cookie cutter style lines where one impression was on to of another.
    Doubled dies may show notching or split serifs at the affected areas.

    These doubled dies are more than one hubbing ( or impression) struck into steel working dies. The areas of doubling do not move or change. Typically, doubled dies do have more than a single device doubled.

    VarietyVista.com has only one DDO, and this is not it.

    Have a look at this post and you can see what a doubled die can look like so you have something to compare.
