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

    BS 1974 S DDO?

    I have found countless 74 S's while cherry picking and this is the only one like this I found. It also has the characteristics of the 74 DDO posted on coppercoins. Just a curiousity

    I see nothing suggestive of a doubled die. What alerted you to this possibility? I also see no listing for a 1974-S doubled die on coppercoins.

      I was comparing it to the 1974 P DDO on coppercoins. The extra thickness of the 97 is what made me wonder is for thats what they determined the 1974 P DDO. I was just curious is all.

        I compared it to an average BS 1974 S that I usually find like this one

          Numerals can vary in thickness due to die deterioration (which makes them thicker) and intentional die abrasion (which makes them thinner). I'd need to see more evidence than this to conclude this is a doubled die. However, some of our more dedicated variety experts on this forum may wish to weigh in with their opinions.
