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

    2011 Kennedy with high reeding?

    Have you all ever seen a Kennedy half dollar, or any reeded coin with a high reeding? It seems more pronounced on the reverse than the obverse. It is sharp. The height as best I can guess is about the thickness of a fingernail. I have managed to take a few photos of the rim.

    As best I can tell with a loupe, the reeding is pretty consistent all the way around the coin, nothing funky going on there, so I doubt it is a "partial collar" since everything looks OK.

    Coin is a bit underweight, but nothing significant, 11.22 grams vice the normal weight of 11.34 grams.

    I know this is nothing major, but I thought I would share it with you.

    The first photo shows the high reeding pretty low at "STATES", then gradually increases to "OF" and remains high past "AMERICA" and further around the coin, past "HALF DOLLAR".

    Below are two magnified areas around the edge showing the high reeding well above the flat surface of the rim.
    Lighting might be a bit low, but this is a Proof coin, with a lot of cameo. Any more light and we'd all be seeing nothing but blazing white.

    Thinking it is a finned rim error. Slightly misaligned dies?

      Plus its a proof. Struck at least twice or more. I would say its just a well struck coin. I wouldnt go as far as calling it an error. The weight is within the ±0.4g tolerance. Great pics. I like the closeups

        I agree...they are awesome photos. I can also relay something I saw on a mint tour in 1999. A new collar was installed in a striking machine while I was there and the differences between the before and after coins was noticeable. The new collar produced nice, sharp rims. Do you think that is a possibility here...especially with proofs?

          Thanks all. The wide area shot was done with my Samsung S9 phone. The two close ups were done with an American Scope microscope and a 16MP digital microscope camera.

          In regards to Bob's question, I can see that as a possibility. I don't know how often they replace the collars, but in this instance and multiple possibilities of it being struck a tad stronger than normal along with the possibility that it has a new collar as well may be the answer.

          I do not know if it could simply be a setting for the collar that was a wee but too tight, or the planchet itself was just a touch larger than normal causing the metal to overflow.

          The edge is extremely sharp, I am a little worried about it punching through a flip, so I placed it in a 2.5 x 2.5 plastic flip so there is a little more room and less stress on the flip.

          Being a proof, I don't want to subject it to a lot of handling. BUT, if I can find the time and a steady hand to do so, I will attempt a photo of the reeding where the reeding is at the highest point.

          Possibilities are endless, but issue is very minor. It's the brainpower behind everyone's contribution here that really counts. I haven't seen one of these in geeesh forever. I forgot what it was called ! Thanks for the reminder SumD.

            You are welcome sir. The reason I called it an error is I had seen an article on them a while back. https://www.cointalk.com/threads/fin...h-post.290930/ The coin from the article's certification page https://www.pcgs.com/cert/12894299

              Thanks Sum. Those ones are pretty extreme there. I ran across one on a Lincoln last night and thought of this thread. Pretty minor one
