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

    1988-P 5c DOUBLE STRUCK IN COLLAR FlipOver

    These are all the diagnostics you should expect to see on a genuine Double Strike in Collar. It was submitted by Tracy Miller April 28, 2007.

    One interesting aspect of in-collar double-strikes that affect 5c coins is that they are almost always fully surrounded by the collar on the second strike. This is in contrast to other denominations which often show a "re-entry" partial collar on the second strike. Any idea what might explain this pattern, Ken?

      Mike,

      I don't think I ever thought about it that way. I do have four double strikes in collar of Lincolns of which all are sans a partial collar. All were the same date, (I think late 1990s) all were from the same dealer purchased by me at the same time and none were anything particularly special in terms eye appeal -- just a nice price.

      Anyway, all I can think of is that the 5c piece is CuNi which may create less friction than copper and for the other denominations we have reeded collars.

      I'll ask a friend of mine that makes dies and strikes coins.

        Full enclosure by the collar on the second strike is not uncommon in other denominations, but it almost always seems to apply to nickels, especially those minted before 1999 or so.

          I'll have to think that one over. Never considered it. Interesting observations.

            I forget which States were involved but Abbott's Coins in Birmingham Mi had a States quarter struck over a different state. It was "full-enclosure" as you call it. I wrote it up for Coin World long ago.
