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

    RI State Quarter seems to be missing clad layers

    Good Day All,
    Newly added member to CONECA.
    Have been collecting coins & currency for some time and have recently expanded my interests to include error varieties.
    This being my first post, I am looking forward to hearing thoughts on my assumptions of missing clad layers and if this is the case, perhaps some ideas on why coin weight seems to be higher on the “missing layer” 2001p RI state quarter, than one seemingly intact. I’ve included photos of coin comparisons and with this being my first post, would appreciate any feedback on content included on this submission, ensuring future posts follow the best practices. Appreciate the time and efforts of those reading and responding. Thank you so much!
