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

    Missing clad layer

    I’m curious because on this 2015 Bombay Hook Quarter it looks like the reverse clad layer is missing but its weight is 5.7g. Thanks for looking.

    @mercergrl2

    I honestly don't know what to think of this one, since it has two different types of look.
    I feel suspicious about this since one is pure copper and dark brown and the other is totally different.
    On the dark brown side, I don't see any actual "dings". Maybe the clad layer was removed chemical wise and light splashed over to the other side?
    BUT, I don't have the coin in had and cannot put it under a 'scope.

    You can wait for other responses as well.
    You can also ask the CONECA staff to look at this.


    I suggest you visit this main forum page.
    Look for CONECA SERVICES
    Go under EXAMINATIONS
    Add a post under examinations. A CONECA staff member should look at the coin.

    ADD as much information as you can about the coin, in text and photos. By doing so, you may get your answer a lot sooner than having to wait for several replies. Add the weight, maybe a photo of some of the reeding (thinnest area/side of the coin) as well.
