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

    Secondary Question

    This coin is a fine example of something I want to know about. The fields (flat surfaces) have irregular "textured" portions on the otherwise flat surfaces.

    What causes this? Is it due to uneven planchet surfaces or is the textured portions caused by dies that are not fully polished? I would think that if the planchet had an irregular surface, the actual coining of the planchet should remove this irregular surface through plastic flow.

    I have found a number of coins with this irregularity from 1999 forward. I have seen it on nickels, dime and quarters. Curiously, I have not seen any quarters before 1999 with this anomaly.

        It could be struck through grease but I would expect a slight loss in relief of the devices, due to grease getting into those parts of the die, if this were the case. I would hazard a guess that this might just be die erosion during the long life of a die, but I can't be very certain.

          actually what happens is when a device of the die becomes partially or completely filled in with grease mixed with metal dust and all kinds of debris falls out of the die it lands on the next planchet and get's struck into the coin by the dies. this is how dropped letter coins get's made at the mint and this is why the dropped letter coins are scarce. most of the time the die droppings don't stay together and breaks up into tiny pieces.

          most of the time when a real dropped letter coin is found it will also have some of this struck thru areas along with the dropped letter.
