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

    I recently found a 1961 double died Lincoln cent. I couldn’t find any info online about it. Only RPM’s. If anyone has some info they could share I’d appreciate it. Thnx

    In my opinion, this is classic machine damage. Some people call it mechancial doubling or machine doubling. No matter what its called, its worthless doubling. You can read more about worthless doubling at

    Https://doubleddie.com look for the worthless doubling section, John Wexler compares doubled dies and worthless doubling. Its a good read.

    The coin suffers damage like this when omething in the minting machine goes wrong. The working dies strike the coin and then either the coin does not clear the working dies properly and the coin takes damage.

    You can see damage, as each number in the 1961 date appears to be thinner. Second, the area that appears doubled is lower almost step like, if you take all of those areas and raise them up to the same height, they would look like a normal coin.

    Typically if the reliable variety coin sites do not have a listing for a variety ( rpm or doubled die) your looking for, it is probably something else.

      Although I cannot find a listing for a 1961 Lincoln cent doubled die I do take note of the split serif on the 6 in 1961. Any opinions on this?

          I believe what you're seeing is when the die lifts away from the strike it slightly twists CCW giving it the steps look of typical machine doubling. This is very common. Like the saying goes "trust the sites knowledge" so if it's NOT listed then it probably does not exist. It's a good learning coin though. Doubling is one of the hardest aspects of numistics IMO because it throws so many people off.

            That last photo is classic machine damage. Its lower and shelf or step like. It looks like damage or parts of the numbers have been sheared off, especially in the middle of the number.

            I suggest looking closely at the extreme versions of a doubled die and look at the heights of each impression. It will show that each impression on that working die was at nearly the same height search for:

            1955 doubled die
            1958 doubled die
            1969S doubled die
            1972 doubled die ( die 001, 002. 008 shows a nice doubling at IGWT).
