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

    The only thing I can see is the Master Die doubling which affects over 50% of ALL 1972 cents. I do not see any RPMs or any additional hub doubling on these coins.

        That's because it is not an extra E. The anomaly in the mint mark is normal from the punch and the 2 is not extra high. If you had read about the master die doubling for the date, a lot of the things you point out would have been identified for you. As far as the extra E, I am afraid you are just seeing things that aren't there.

          This is all normal. Maybe some machine doubling on the E in WE. Otherwise normal stuff for 1972...
