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

  • 1972 S Lincoln Mintmark Error

    Can anyone help me out with what’s going on with the mintmark doubled, triple or rpm? Thanks in advance. 2D906801-E07F-43DD-9211-2F8FA44FA9F9.jpeg

    Hello
    We're here to help and add my two-cents worth.
    Thanks for posting.

    Look at the back of the "9". It suffers from some sort of damage.
    The damage probably went in between the back side of the "9" and damaged the left side of the "S" mint mark as well.

    You would be able to look these up yourself for a match at either https://doubleddie.com, https://coppercoins.com or http://varietyvista.com .

    Variety Vista has three RPM's listed. Two are on proof coins, and the only candidate that would fit does not look anything like your coin.
    Have a look:

          In this case, it is just a damaged coin, It is not a variety or error and has no premium associated with it.

            As Bob mentioned its simply damage.

            Yes, there is a lot of confusion about the differences between doubled dies and machine doubling but the very simplest answer is this:
            Doubled Dies are multiple impressions on a die, the die is then added to a minting press, and it makes doubled die coins until the end of its service life. When looking for doubled dies, this means more than likely the impressions you see on the coin should be close to the same height. Doubled dies tend to add thickness to letters, numbers and devices on a coin and may show split serifs (notching) and possibly a "cookie cutter" style line through letters.

            Mechanical doubling/strike doubling aka worthless damage tends to make the letters thinner as some of the material may be sheered off. Worthless doubling tends to be a lot lower than the initial impression and shelf or step like. Some of the worthless doubling is caused by extremely worn dies that almost look fuzzy due to being near the end of the service life (late to very late die stage). In some cases areas of the coin exhibiting worthless doubling can look like a mini-payloader traveled around the coin removing parts of the letter or features.

            John Wexler's site offers a few examples of what a double die looks like and then, what worthless doubling looks like.
            Check this out....and notice the split serif letters and the cookie cutter style lines on the doubled dies. WARNING ! Not all doubled dies will look this classic, but the rules still apply !

            https://doubleddie.com/144822.html

            If the area looks low and shelf-like, suspect mechanical doubling/strike doubling.

            It is always best to try to self attribute any coin you suspect as a doubled die.
            Check https://varietyvista.com to see if there are any DDO's, DDR's or RPM's that may be a match.

            The staff on this CONECA forum are always here to help, as well as seasoned error and variety collectors. Simply post a really good photo of the obverse, reverse and if possible, the area in question. Not too much magnification or lighting a clear photo is always better than a blurry one.

              I appreciate the knowledge & information you guys have to share..One last question lol if I am looking at a Lincoln and the date, words, image etc, appear twice as high or extra height & width than it normally would be, that is a doubled die coin than correct? the issue I have looking at the pictures of doubled dies may be due to the viewing the coin straight down at the coin like looking down a microscope, half the time I don’t know if it’s due to me being colored blind but some of the photos I have a hard time seeing the split serifs opposed to looking on an angle where I can take notice right away to the doubling such as thick dates or “liberty” or other areas.. Thanks again I appreciate the assistance..

                There is no 'extra height' associated with a doubled die. It is simply a doubled device, seen perfectly from straight on. Not all serifs will be clearly visible either. It all depends on the strength of the doubled hubbing. Separation lines can be weak or strong too, but they do add to the thickness of the devices.
                I can strongly suggest that you take some time and go through the listings either here on Variety Vista, or sites like coppercoins.com and doubleddies.com (Wexler). Look carefully at the photos and the descriptions to see how they come together. The more you look at, the more you will understand how the minting process made them and soon enough, it will become second nature to be able to tell the difference between true hub doubled dies, and other anomalies. It takes some time, so be patient and enjoy the hobby.

                BTW...Being color blind should not have any effect in being able to spot a variety. Some folks consider it a blessing.
