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

    1997D 10C doubled die

    This looks to have a 1%-2% CCW hub doubling or hob gobbling on 'E' & 'D' in ONE DIME. There's doubling in bottom of olive branch and bottom of torch leftside.
    It has a double eyelid.
    The 'D' has what looks like a split sherif and doubling.

    In my opinion, I looked at varietyvista and conecaonline.info and there were no documented listings on either.
    I will review the 3rd photo again. It looks lower and step like to me.
    The eyelid to me looks like die deterioration, it does not look split.
    I dont know if the Roosevelt series has eyelid DDOs. Lincolns do.
    I personally dont collect (nor look for) eye, ear, column or post 1996 doubled dies.

      Isn't a second hub pressing going to leave the cookie cutter effect like that with it being just slightly lower BUT not leave a shelving effect from machine doubling with the single hubbing now?
      I'm not arguing just trying to get better pictures to discern doubled dies from machine doubling so that I don't post repeat posts of MD as well and waste time from knowing better is all.
      Can you comment on the mintmark on why it looks like a 2nd "D" is present in the upper loop please because they're doesn't seem to be any drag or flow lines.

        This is a 1997 from Denver. Its more than likely in the single squeeze hubbing era.
        It more than likely will not appear the same as the multiple squeeze era that ended in 1995 or so.

        I know you are not the type to argue, but the first thing I do is check references.
        I have to trust the resources and collectors have found 99% if not 100 of the varieties, especially after two decades.

        Based on that, and with little to go on in the Roosevelt series for varieties, its difficult to assess what a Roosevelt doubled die will look like with the single squeeze pressing. From 1990 to present, there have been zero doubled die obverses listed on variety vista. For DDRs, its been zero from 1990 to 2014.

        Every doubled die is different. What people see with coin in hand and what is represented in a photograph is sometimes different.

        I also am slightly confused as you have photographs of possible doubling on the obverse and reverse. If I may ask, do you consider your coin a DDO, DDR or both ?

        Although the D looks a little different, I personally do not see a split "serif" on the D.
        That upper inner loop of the D appears to be a different color and might be debris related. At your own risk, you may be able to use a tooth pick to see if whatever it is can be removed.

        I believe the working die may have lifted slightly to the north and the coin was left with a slightly weird looking mintmark. The mint marks were added to the design, so its more than likely not a RPM. If the mintmark was doubled, the rest of the obverse would have to be scrutinized for a doubled die. Yes, I realize that this is what you are trying to convey, but I just dont see enough here to say it has potential. Again, thats my opinion and I have been wrong in a few handful of assessments over the past 4 or so decades.

        Lets see if Eric eaxtellcoin can explain it better, or offer his expert opinion on this.

          Now that this website is done with its hiccup, I will attempt to add my opinion on the reverse. The lower left side of the torch is extremely lower and in my opinion its some form of damage.

          The dot of EPU looks damaged at the bottom. It looks like the working die lifted to thenorth east and slightly damaged some of the devices.

          It looks like the very bottom of the L appears to be the same. For the U, look at the right leg at the center. The right side all the way to the bottom center of the U, it almost has a "torn" look to it.

          The right leg of the U at the top, looks like there's some extra metal there but I personally am not sure of the cause of it. It could be extra metal seeping out of a working die, from die deterioration. I believe it happened on the I as well.

          One last thing. If you believe these coins to be varieties, whether they end up being one or not, they should be in the varieties forum. Otherwise the CONECA staff members will eventually move them anyway.

          Happy hunting.
