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

    1969s

    Here is another.

    I'm sure you going to tell me this is a lamination Error.

    If you have ever worked with Material that delaminates, which you probably have not. This is not even close.

    I am only posting facts and not just because "it has always been that way"

    I will be publishing an article with hundreds of example disproving old theories.

    When copper is exposed to high heat and pressure, it undergoes oxidation, resulting in a range of colors including dark orange, pink, blue, and even silver.

    Go back to your science classes. Respectfully

      There was many variables that struck this coin over others. Heat, Pressure and others.

      No two coins will not be struck the same.

      Your overlays that you recommend are specific to one coin that it was templated from and not all coin in the same year and mint.

      The odds of two coins being struck the same identical are astronomical with all the variables, Pressure, Heat, RPM (revolutions per minute) power surges, Planchette size and weight and many more.

      Each coin would have to be struck in the exact same environment and variables.

      They can't even get proof coins perfect.

      The only ones are the ones that had the perfect condition or variables and stike

      Something to ponder.

      Visual is the best inspection
