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

    Die deterioration channels on top of overlapping images?

    I just found a 2007P Roosevelt dime and on the reverse, the highest triplet cluster on the right side of the dime has cast deterioration channels onto the third and furthest right of the 3.



    Has anyone heard of this? Deterioration cannels not onto the field but onto another overlapping image?

    Apparently after consulting AI on Google, these things (wear channeling only on one side of a reverse face or obverse face and THAT wear channeling coming on another image and not in the field,) are signs of a counterfeit coin. I'll post pictures when I can.

    It's strange I was lead to believe I was so sure because the creation of the die chips around the mouth just like a real dime were very normal looking.

    I can see the counterfeiters used the sight of the die chips and they imply that they were a very common thing back in 2007 but they didn't become a very common thing on the face of a dime until about 10 years later.

    They used what was recognized now.
