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

  • 1974 D Kennedy Half DDO

    Here's a nice circulated 1974 D DDO Kennedy Half. I found it in some old coins that I have had for many years. Before I ever knew about error coins. It appears to me that most, if not all, the letters and date on the obverse are doubled.

    This very well may be CONECA I-O-I. There's no doubt it is a doubled die, and I believe there is only one variety listed for the obverse of 1974D.

    I have one some where around here, and I will see if it matches your pics.

      Thank you Bob, for the info. I know nothing about error numbering so I'll have to check it out. I might be able to enlarge the pics if that will help, or I could email higher dpi pics, if you like. You made my day. Thanks again!

        OK...I found my copy of the 1974D Half dollar variety. Here are a couple of marker photos. See if you can find them on your coin. BTW..This is a Cherry Pickers listed variety.

          Bob... I'm not sure that I know exactly what to look for on the coin. I assume
          you are referring to the tiny die crack looking marks the arrows point to, right? I have rechecked the coin thoroughly and do not see any marks that
          look like the ones the arrow are pointing to. There are some very faint scratches on the obverse in the area you pointed to but they look more like
          straw marks. I've tried taking close-up pics but haven't been able to get any
          clear enough to show these marks. I do notice some, what I would call, light doubling of Kennedy's profile. I have another Kennedy Half, can't remember which year, that I posted which also has what appears to me to be profile doubling but Mike D. said that it was MD. Is it possible to have DD and MD on the same side of a coin? Thanks again!

            Since both machine doubling and a double die are created at two different times (after the coin strike and during hubbing, respectively) it is possible to have both conditions on the same coin face.

              The pictures I sent with the arrows point to markings that would be present on most coins in the same die state. These are called markers and are used to positively identify your coin to the variety listed. This may or may not be true in all cases.
              I can say with some certainly that your coin is indeed the doubled die I mentioned. There have been no other 1974D doubled dies reported for this Kennedy half, and I doubt that something this strong could have been missed by the collecting public after 35 years.

              If you would like, and if you are willing to send it to me for examination, I can attempt to positively identify it for you. If that sounds like a plan, email me at mustbebob1@embarqmail.com and I can give you the specifics.

                Searching4errors…your half dollar does look like it is the 74D DDO-001 (see photo). Bob’s photo of a marker, the die scratch coming from the arrow appears to be a Stage B, MDS (mid die state). The Stage A, EDS (early die state) does not have that marker…no die scratches around the arrow. The Stage C, LDS (late die state) has the die scratch marker coming from the arrow and also has two die scratches between the top two arrow heads (see photo). You should be able to confirm your half dollar using these markers.

                The 74D DDO-001 does not have any doubling on the profile, if yours does it must be MDD (machine damaged doubling)…like BJ talked about.

                  Thanks Larry, for the pics. I think you may be correct that mine is the 74D DDO-001. It does look like your 1st pic although I don't know that mine has quite as much separation in the letters. There is a tiny bit of light MD around the eye and cheek. I don't find any cracks or marks anywhere around the arrows. I've attached a couple of pics. One of TRUST (not as clear as yours) and one of the Arrows. Thanks! I appreciate your help.

                    Fran…although circulated, it looks to me like the reverse of your half is an EDS, which is probably why you don’t see any die scratches around the arrow heads.
