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!

The March/April 2021olor issue of Errorscope
has been added to the members only section of the site.

CONECA reorganizes how it administers its Master Numbering List of error and variety coins and now offers Attribution and Examination services through the CONECA Forum.

As of November 23, 2020 the non profit Error and Variety organization CONECA, reorganized how it administers its Master Numbering List of error and variety coins and is creating a new management system for cataloging and submitting coins for consideration.

CONECA is NOT changing current numbers in the Master List already assigned. All current CONECA numbers remain the same. Only new attributions and new numbers will be added as new varieties and errors are discovered.

We are only changing the way CONECA Attribution and Examination services are provided.

New CONECA numbers will be issued through a CONECA Master List site currently being developed. The CONECA Master List and CONECA numbers will no longer be managed, attributed or issued through varietyvista.com. CONECA members and non-members can submit coins for Attributions and Examinations through our CONECA Forum home page in new sections created specifically to look at new submissions.

The Attribution fee is being rolled back to $4 per coin for CONECA Members and $6 per coin for non Members plus shipping costs. We encourage you to join CONECA and the exciting world of varieties and errors before your first submission and save while supporting us. The reduced Members fee quickly pays for your CONECA membership.

Attributors and Examiners that have been listed in prior issues of Errorscope or the CONECA website should not be sent coins or contacted directly. When a submitted coin has been looked at and confirmed through the appropriate Forum thread a CONECA Examiner or Attributor will be assigned and mailing instructions provided.

We look forward to helping you identify your varieties and errors as we take this exciting new step.

Well, 2020 is now behind us and I am sure everyone
is looking for better things in 2021.

1934-D Peace Dollar VAM3 Top 50
By John Cava

This Peace Dollar is one of my favorites. It is another Top 50 that has some shared characteristics of the “King of Peace Dollar VAMS” the VAM 4. The attributes of this variety are mostly on the obverse.


The CONECA Master List
Variety Philosophy, Approach and Methodology
By Jason Cuvelier, Lead Attributer

CONECA, over the past several decades, with the assistance of numerous contributors, has created the CONECA Master Listing (CML). The CML is comprised of numismatic varieties and design changes found on 19th, 20th and 21st century coinage minted by the United States Mint. Varieties CONECA focuses on tend to fall into a subset of error numismatics that involves one or more mishaps on a die (though sometimes a working hub or punch) during the minting process, typically during pre-production, that impacts all coins minted with that particular die. CONECA catalogs these varieties, we call these “listings” and create additional entries that we would designate as “NEW listings”.

Have I Stumbled Onto Something, or is This the Most Worthless Error
Ever Found on a Quarter?
by Mark Benvenuto

I’ll readily admit to two things: I am a complete science geek, and my family knows my passion for coins is deep enough that they often bring me anything new or different that they come across in change. My son David presented me with three Vermont-P quarters that he received from a Best Buy store in Madison Heights, Michigan on December 2nd, 2020…

Treasures Among Treasure
2000 Prototype Golden (Sacagawea) Dollar FS-902
By Dr. Ron Brown

Left: Business Strike Reverse note smooth appearance of neck and tail
Right: Prototype Reverse note feather texture of neck, wings and tail

With rare exemption, I always write about coins I own. This article is no exception and from my ownership, I observed and learned a few things that I feel should be said again about this rare and very desirable variety.

Multiple Error Tokens/
Multiple Error Types
by Denny Polly

One of my favorite error types is Token Errors of Multiple Types (meaning Clips, Cuds, Off-Centers, Double or Multiple Struck, Overstrikes, and others) on Multiple Types of Tokens (Car Wash, Civil War, Game, Hard Times, OPA, Sales Tax, Trade, Transportation, and others), thus the article title of “Multiple Error Tokens / Multiple Error Types.

2020 Nickel Variety
By Elliot Mitchell

Howdy fellow error collectors! I am writing this article to notify y’all of an interesting, modern variety that I discovered earlier last year.

1960 D/D Lincoln Cent
By Preston Thomas

One of the lesser known numismatic marvels of the 20th century is the 1960 D/D Lincoln cent. There are a multitude of 1960 cent errors and varieties, but this is one of the most sought after. In my opinion, not only is it one of the most interesting coins in that year, but the most fascinating Lincoln cent in its entire series. This is due to the fact that not only is it a RPM (re-punched mint mark), it is also a DDO (doubled- die obverse).

Coins That Are Considered Wrong Die Varieties, Transitional Die Varieties, or Mid Year Die Changes
Part Three: The Dime
by John H. Miller Jr.

In the second part of this six part article we looked at Nickels. In this part three of our article we will be looking at:
1) 1964 Philadelphia and D Pointed 9 Dimes
2) 1968 San Francesco Reverse of 1967 Proof Dimes
3) 1969 Philadelphia Reverse of 1968 Dimes
4) 1970 Philadelphia and 1970 Denver Reverse of 1968 Dimes

Young Numismatists Program
By Logan Wostyn
Hello Everyone!
I have 1 package headed out in the mail for the 1 kid that responded last month. They will be receiving a few error coins. Remember I have error coins, loupes and scales to send out as prizes and I always send more that 1 item. Come join the fun and send me an email.

This issue I’m thinking a of a short quiz. Name the State Quarters that have known errors and what the errors are. As usual those that respond correctly will receive a package from me with error coins.

This is an easy one guys and we have lots of new prizes that have been donated.

Hope everyone stays safe.
Your YN Director

Cuve’s Round Up 14
By Jason Cuvelier

Jefferson Nickel 2020P DDR-001 (1-R-IX T2)

As the new lead attributer for the CONECA files I am taking the opportunity to alter the title of my article, shortening it to just “Round Up” and introducing Attributer Bob Piazza as part of the new team we are assembling. Showcasing this article is our first new CONECA number in the Master List (the CML). This new variety listing is a nice 2020P Jefferson Nickel that was sent in by Stephen Young, who is coincidentally helping me with clashes. This will also be the first listing I am designating as a Class IX. In the future I will post an article on single squeeze doubling and outline my argument why it should have its own designation separate from Class VIII. Below you will find a strong DDR with most of the central portions of the design distorted. The rest of my article will focus on varieties I have documented recently.
