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

    Where did the name 'snail foot' come from? Have you attempted to clean off this appendage?

      Just thought it looks like a snail. No. It is raised under the D mm.

        Something is on the coin. Possibly corrosion. Its not part of the MM

          It has some corrosion being a steely. The brown in the MM area looks like a little rust. Found in Coinstar machine. MM strike is over the anomaly which is also raised. I find it interesting that the foreign object has very distinct lines and not just a chip or residue blob.

            Since these coins were zinc plated, it is possible that the anomaly was on the planchet before being struck. It would be like the gas or corrosion bubbles we see on modern coinage. I agree it is different and the straight(er) lines make it more so. Is the rust in that area the only area on the coin with rust? If it is, it may be a clue that it is a plating issue.

              Yes there are a few more spots on obverse and reverse. It’s the straight line shape that intrigued me.
              Thanks for your thoughts.
