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.

    Looking for clarifiction on die doubling

    Hello,

    Can anyone comment on the photos I have attached herein on whether or not the two different coins qualify as die doubling? I tried to post elsewhere to confirm what mechanical doubling is or what I thought it may be, but was asked to create a new post. Sorry if I stepped on toes, but I'm just trying to learn protocol as I am new to this forum.

    Thank you for your assistance in advance.
    Ernie

    Ernie,
    Strike doubling or mechanical doubling is always flat and shelf like. In other words you have a flat area before a slight raised area.
    1968-1973 rolls are jam packed with MD coins. Even though you photo is out of focus, I can tell this IS MD.
    Sorry, Eric

      Eric,

      O W that's what I thought. I appreciate your taking this on for me. I will go to the Die Variety Forum and do a lot of research.

      Keep collecting
