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

    Mike,

    I must admit that this is the most honest answer I have gotten from this Forum. I also will admit that you are a honest and worthy person that will give a honest opinion (Depending on the coin) that I have seen. I am learning your knowledge though it is slow here.

    I honestly think your a smart guy but we all have our limitations. Don't you agree?

      Mike,

      We must all consider BJ's CD as a starter for understanding how traildies are formed. I understand it for I work with metals, heat treat and finish the final product. I also understand how friction heat vs. coolant vs. pressure vs. movement that comes from the fore mentioned. I would like to say that I am alway's open to question's as long as I have been informed on what the anonomly is.

      Some thing's in the past are simple, (it is a learning process) but with time all will understand if we understand each and everyons explanation.

        I have thought in the past that certain element's of machining vs. actual production........ the heat transfer from the die(I see it every day, I won't give it away) consists of a heat transferrable material. I do know how heat is transferred away from the working part. BJ, you are correct in every way you have explained the Die. There are US Mint worker's and or Goverment worker's scanning this. It does make it fun.

          My practical knowledge of carbon steel came from the study of HY-80 steel aboard submarines. One takes a keen interest in such an encasement when it is the separation point between a lot of water and your life. Plus, with ample reading time (there is little to do except eat, read, sleep and stand watches on long deployments under water), you have a tendency to expand your knowledge into areas that would not be considered in a "normal" life.

          I do thank you for reading the CD on the formation of trail dies. While there may be some areas in question concerning how they are formed, it seems that no other explanations have been in the offering, even from the U. S. Mint. So, in the end, we must go with what sounds the most logical.

            BJ,

            We both have to assume what we know. We both read to find the element's that surround us or work with to know how safe we are. I applaude you for your service.

            With technology the way it is today, the input I hear, the different variables I see with metals, I am inclined to push the envelope a little futher.

            Your CD is dead on to the extent that it is common knowledge to me but I am willing to help if you persue it futher.

            As you say BJ, "This is what sound's most logical"

            This is probably a dead subject now but I beleive it is important to find the truth on how the production is performed. It can not be that complicated.

            Thank's Bj and Mike for your responses.

                Asuming is optional to finding the truth! Thank you for the diggiing on finding a actual die.
