CONECA to Offer Free Examination of Error & Variety Coins at Major Coin Shows Across the USA
CONECA, the international error coin and variety club, will be offering free examination of error and variety coins to collectors at educational tables at coin shows across the United States throughout this year and into 2026.
The club, whose name stands for “Combined Organizations of Numismatic Error Collectors of America,” is the largest coin specialty club in the United States and has actively been educating collectors about mint error and variety coins for the last five decades. They would love to help you with your error coins!
At their coin show tables, different members of the CONECA Board of Directors and other error / variety enthusiasts (each with different areas of specialty as available) will offer free examination to collectors who bring coins from their collection to the show with questions. This is offered as a free service to help the hobby grow.
CONECA is devoted to education about errors and varieties and will not be buying or selling coins at their tables. The club requests that collectors have an idea of what they are asking about on the coins they bring to the shows, to allow for as many collectors as possible to have a chance to have their coins examined. The show schedule is as follows…
There will be a CONECA table at the Fall Pennsylvania Association of Numismatists (PAN) show October 16-17-18th, 2025. The show will be held at the Monroeville Convention Center, 209 Mall Blvd, Monroeville PA, 15146. More info at https://pancoins.org.
CONECA will also have a table for the first time at the fall Willamette Coin Club show in Portland Oregon. The show will be held November 15th and 16th 2025, at the Holiday Inn Portland at Columbia Riverfront, 909 N Hayden Island Drive, Portland, OR 97217. For more information see https://pdxcoinclub.org/portland-coin-show
CONECA will also have a table at the winter FUN show, January 8th-11th, 2026, in Orlando Florida at the Orange County Convention Center, 9800 International Drive, in Hall WC, Orlando Florida. More info at http://www.funtopics.com
In addition, CONECA board members are occasionally available to offer educational programs about error and variety coins, both virtually and in person, to local coin clubs nationwide. Please inquire if interested: minterrors@gmail.com
We have a new set of medals to offer our membership
These are limited to 50 each and they are being offered to members only until May 15th.
After that date, we will open up orders to non- members if any remain.
Purchase using Paypal. If you want to pay by check or money order, please email me so I can reserve your order because I am pretty certain these will sell out quickly, and orders are first come, first served. We have a silver round celebrating our 40th year which we had struck over the leftover 30-year rounds that Ken Potter had purchased from the club ten years ago. Then we had two different copper rounds made: one from the new 40th Anniversary die and the other as an over stamp with 40 over 30 and the dates changed. See photos! Remember there is only a mintage of 50 each. Shipping will be $6.00 for 1,2 or 3 medals.
Cost is $65 for the silver round
Coppers are $25 for a set. 
Welcome to the CONECA Web Site!
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 those pages on our site! We thank everybody who has helped make CONECA the great success that it is today!
