A subscription to the club’s award-winning journal Errorscope, published six times a year, is available when you join and become a member. Please go to our Join or Renew page if you are not already a member and wish to get our publication.

If you are a member and interested in submitting articles for publication please see the guidelines below.


Submission Guidelines

If you need to send only a paper copy of your article, please try to send typed copy that is clearly readable. A legible handwritten copy is also acceptable. Send scanned photo files or actual photos with your material. Do not send a printout or photocopy of a photo as these cannot be used in the ERRORSCOPE. Please contact Allan before sending any material to obtain a valid shipping/mailing address. When taking photos to accompany your material, use a background of a contrasting shade (i.e., light background for a Lincoln cent, dark background for a Jefferson nickel).

Note to authors/publishers: CONECA is also interested in publishing news releases highlighting current stories published elsewhere that are associated with error-variety coins and/or the minting process. Interested authors/publishers are encouraged to email an abstract along with a photo(s) and details of when and where the article was published to the CONECA webmaster at: Only email submissions will be considered.
