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

    Does this look like machine doubling or is it DDR ? Thanks in advance. I cannot find any reference to this error. Not the best looking coin but I want opinions before I send To Dr. Wiles.

        no... the coin is damaged.
        It's not an error, its damage that occurred when the dies struck the coin.
        It happens more times than many people realize.
        mechanical doubling, mechanical damage, strike doubling are all worthless doubling.

        This is just one website devoted to educating the collector:

          Thank you , Gary !!! Appreciate the input. BTW , I did find one similar, almost duplicate, on Ebay yesterday. If there is more than one ....does that mean the machine was broken and just producing damaged coins? Curious. But thank you kindly...I do appreciate the feedback.

            Machine doubling is damage, but....its a condition that is introduced into a rather normal operation that can cause the timing to become off and as coins are struck, being ejected once struck, or one of many other possible scenarios.

            You have to realize how fast these machines work, to make billions of them per year. They typically are faster than a rabid jack hammer.

            The machine doubling - worthless doubling can plagued a minting press for seconds, or a long period of time. They are machines, tuned by humans, and then left to mint hundreds of thousands of coins.

            t's way too much to say in a post. There are some good books to read, especially..
            The error coin encyclopedia.

            https://books.google.com/books/about...d=9HryPwAACAAJ

            The second edition with Fred Weinberg, has a plaid dust cover. They pop up on used book stores on line. I bought mine from Fred W. Off his website and he autographed it for me. It's a great reference.

            You can also research what you ask here on your fav search engine and learn as much as you wish. Understanding the minting process....either before 1990s or afterwards is two different techniques, but same basic process.

            In my opinion, some people prey on the unknowing and either sell machine doubling as something it is not, or, they the selves may not know what it is exactly and may try to sell it in hope to get something more than face value for worthless doubling. Could they be held liable? I do not know.

            We are here to help, but if the poster can help themselves as well, that is a win - win.
