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

    Is our 2003D LCM Doubled Bldg Corner not an MDD?

    Mike , All,

    Have magnified our previous posted image to show potential
    offset doubling (???) and not MDD.

    The RIGHT URN (not photographed) is also doubled (offset is same direction as the clorner doubling).

    Your clarfication or reconfirmation of why it is MDD will be appreciated .

    Thanks!

    On these images I really don't detect any doubling. I'll let our resident variety experts chime in, should they so choose.

    I do think you're looking too hard.

      Yes, you are looking to hard. The corners of the stylobate (the levels under the first three and last three columns) do have a raised quality, so that is normal. The other "doubling" seen seems to be a very slight plate ridging from the strike or it could be the formation of die deteriorotation doubling. Either way, it is inconsequental and does not qualify it as a die anomaly.

      The biggest thing that you must do is realize the difference between striking anomalies and die anomalies. This will help you immensly in your quest for the doubled dies that you so actively search for. As Alan Hebert put it " In 999 cases out of a thousand a new discovery will be MDD rather than a die variety". Since the advent of the single squeeze process, that figure may have come down a bit since there is a seemingly multitude of minor doubled dies, however, the vast majority of doublings seen are of the machine variety and not create from the hubbing of a die.
