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

        Thanks so much for your very educational article. I've learnt a lot about doued die versus mechanical doubling & more.
        I however didn't see a clear-cut section re 'weight'. So your response "within tolerance" is appreciated. I had no idea that 0.15g was within tolerance, now I know.
        Thanks again.

            I use +/-5% as a guide for a coin being within Mint tolerance. Also some metal typically is lost due to light circulation. Just what I go by, the Mint and the experts may have other guidelines.

                  2 grains is .13 grams so it is slightly under by .01 gram. Not very much to be anything collectible

                  How did the one liner feel Gary? Lol

                    Well, here is my response, and no, it's not a one liner. HAH!

                    Like I have said in a PM, It's all about getting an answer to a person that can comprehend it.

                    You and I have come a long way. Many years of experience.
                    I personally refuse in most cases to think everyone can comprehend a one line answer.

                    We may know it is factual, but that is through those learning curves, thousands of successes and a handful of failures along the way.

                    The person who may not know enough about the issue simply has a handful of words. They read those words look at the coin, may write on the mylar and put it in a "maybe" box and hold onto it. Some may surf for a more clear explanation, but the words they choose may take them off course. So, in most cases, they come back with more questions about that same coin or others with the same type issue. Some may get discouraged along the way and just toss the coin and drop varieties and errors all together - this happens more times than most want to admit.

                    When I am set up at shows, and I used to give one line answers, that is my analysis of decades of experience. But I paid attention to the atmosphere, it evolved - Now, if the promoter and dealers know I am at the show, they come over or send just about every error and variety question over to me. I answer questions at the level they can comprehend. Some have turned into clients and many ended up coming back at a later date with a simple "thank you again" or a single/ multiple coin purchase. It's all good.

                    Some of the people I have interacted with may only have minutes of this experience. I watch their reactions and can instantly tell if they grasp the answer, or I immediately pick up a few teaching tools out of the CONECA case and carefully explain the issue to that person. Before I realize it, in most cases other people, usually 3 or more are close and listening as well. So, learning does take place.

                    I do that extra mile to hopefully squelch similar posts from the same person. It may aid them in identifying the condition next time and not have to post about it.

                    For me - one liners happen when that is what I see is offered by the poster. If they are not willing to go that extra distance, some times I feel that I will not either.

                    I try to help as best I can, during the times I can. It fosters better communication within the numismatic community and people hopefully comprehend the answer and then say "wow that is so cool"..... and they become hooked, another collector is added to the masses.

                    Job done right the first time.
