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

  • folding roll

    Mr Diamond couldn't see my other pics maybe these will be clearer.

    It's definitely not a rolling fold (blanking burr). A rolling fold will appear as a low, broad, symmetrical tongue of metal that protrudes into the field. It will be surrounded by a fissure. The edge of the coin will be unaffected. I have, in fact, never seen a bona fide rolling fold in a zinc cent.

    While it's clearly not a rolling fold, I can't tell from here what it is. The area of interest is too small to see many details.

      If I'm understanding you correctly a rolling fold would be similar to a cud but would have the design on the error area? I see that on page 162 in The Error Coin Encyclopedia my coin does not look like that. However on page 164 the error pictured is very much like my coin.

      I think I may have a coin with two errors. Starting above the word trust and extending almost to the date on the rim it looks like metal has been folded over on the rim not extending to the field.
      The other is the bevel from rim to field with design elements in place extending from the O in God to the E in We.

      Mike would you be interested in looking at the coin and and passing on your knowledge?

        The outline of a rolling fold would be similar to many cuds, but a rolling fold is not raised above the surface. Despite having coined the term "rolling fold", Arnie Margolis has difficulty distinguishing between rolling folds, retained cuds, and assorted forms of planchet damage. The 1972 half dollar in his book is not a rolling fold. It actually looks like post-strike damage. The three nickels he photographed ARE rolling folds.

        I'd be happy to examine the coin for you. Just contact me at mdia1@aol.com.

          Now that I have it in hand, I can say with certainty that the 1983 cent does not have a rolling fold. Instead it shows a "die attrition error", a form of die damage. The edge of the field portion of the die next to "IN GOD WE" was worn away by repetitive collisions with the beveled entrance to the collar. At some point the obverse die must have been misaligned. An unusual number of die attrition errors appear on 1983 cents. Some are far more severe than this, with half of letters being removed.

            Is that also the reason for the raised areas on the rim between the T and the date from 2 oclock to 3 oclock? I know the seeming doubling of the rim in that same area can come from a misaligned obverse die striking the collar or something similar, but I've also seen the erratic raised areas on some parts similar to this one.

              The raised area on the rim is either a rim cud or, less likely, a portion of a low fin that was folded down after the coin was struck.

                Noted, thanks for the info. I'll see if I can dig up the dime I have with a similar thing and post pictures of it. The lack of blanking burrs on zinc cents makes sense with the plating process being after the blanking (i think?). Though with as many ways as the process of making coins can go odd, I never say never, who knows what might turn up one day.
