Where’s the CONECA Master List

Without a doubt that’s been the most frequently asked questions those of us on the CONECA Board have heard these past 2 years. Sometimes many times in one day. It’s not an easy answer and after finally being able to create, test and now launch the new site we hope you find that your patience has been worth the wait.


For many years the original Master List was presented as text only variety listings with no images on a series of html pages. We had to translate those text files onto a data base driven platform that allowed us to more easily search and access information. To properly make the Master List we wanted to merge a varieties text with its images. We’re working through 190,000+ denomination images shot over 30 year to cull, improve and add to them. All denomination images will be added as completed but going through them is an intense ongoing process. 

— Lincoln Wheat Cent Doubled Die Obverse Varieties (DDOs) and Doubled Die Reverse Varieties (DDRs) are complete and posted
— Lincoln Memorial Cent Doubled Die Obverse Varieties (DDOs) and Doubled Die Reverse Varieties (DDRs) are being worked on
— Jefferson Nickel Doubled Die Obverse & Doubled Die Reverse Varieties (DDOs & DDRs) are complete and posted 
— Jefferson Nickel Repunched Mint Marks (RPMs) are complete and posted with new additions
State Quarter 1999-2008, D.C. & Territorial Quarters 2009, ATBQuarter 2010-2019 are being worked on

A denomination is now accessed from one page. From that page, one text box allows you to search by Date, Mintmark, Date-MM, CONECA Number, Mint location (Denver, Philadelphia, San Fransisco), Year + DDO, Year + DDR, Year + RPM, DDO-xxx, DDR-xxx, RPM-xxx, DDO, DDR, RPM, OMM, Die Type (PR, Satin) or any similar combinations of title key words. Each variety links to a page with its information and images. Search examples might be:

Type in the year only and all varieties for that year will be pulled up
Year and MM (example — 1938, 1938-D, 1944-P, 1938-S)
Year and Die Type (example — 1959 PR, 2005 Satin)
Year and CONECA Number (example — 1938 DDO-001, 1940 RPM-001)
Year, Mintmark and CONECA number (example — 1940-D RPM-001)
Mint Location (example — Denver, Philadelphia, San Fransisco)

We hope you enjoy and utilize the Master List!

CONECA would like to thank (in alphabetical order) Eric Extell for his work sorting through, organizing and adding to the Jefferson Nickel RPM images and variety listings; Al Raddi for his work sorting through and organizing the Lincoln Wheat Cent and Lincoln Memorial Cent DDO & DDR images and variety listings and Stephen Young for his work sorting through, organizing and adding to the Jefferson Nickel DDO & DDR, images and variety listings and the State, Territorial and ATB Quarter images and variety listings.

CONECA is actively looking for help. Members with extensive knowledge in a specific denomination(s) or die stages can volunteer to work with us on this project. Or if your skill set is with content management systems and databases we’d like to hear from you. If you’re not sure but seriously interested in content management I’ll train you.

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 November/December issue of Errorscope
has been added to the members only section of the site.

President’s Message
James Motley, CONECA President

CONECA was notified that Patrick Glassford passed away on September 6th. Pat was a longtime mem- ber of CONECA and was an expert in Canadian errors authoring numerous articles on the subject. He was a frequent attendee of the Errorama throughout the 1980’s and the go to person for anything Canadian related. He was awarded FUN’s Best of Show for his type set of Canadian Wrong Planchet Errors and he was the force behind two Facebook groups related to Error coins of India and Error coins of the world. What was little known about Pat that was he was a Native American with his tribe located in North Canada and held the title of Chief for the tribe for many years. He will surely be missed by those who knew him and his knowledge of errors. RIP (by Mark Lighterman who knew Patrick for decades)

Treasures Among Treasure
Toned Coins A Variety or Error, The Questions?
By Ron Brown

I’m not sure when this fascination with toned coin came about but it reminds me of an incident I observed very early in my medical carrier.

Rotated Die Coin Measurements
By Michael S. Fey, Ph.D

I thought I knew how to measure coins with a rotated die, but I was mistaken. Sure, with practice I could get close, perhaps to within 5 degrees, but I found a much more accurate and standardized way was possible with the Leroy Van Allen RotaFlip ™ Guide and Booklet.

Seated Liberty Quarter a “Pickers Paradise”
By Patrick Jenkins

I was very fortunate as a kid to have a newspaper route. Back in the early to mid-sixties delivering as well as collecting for the papers gave a YN a chance to fill their three fold blue Whitman’s albums. You see until late 1965 and even into 1967 one could fish 90% silver out of one’s collection bag. War and buffalo nickels, and Washington standing liberty quarters, Walkers, and Franklins halves. In your pocket a rub- ber banded roll of bills, silver certifi- cates, two dollar bills as well red seal notes. Once in awhile one can find older specimens Barbers coins in all denominations.

Promoting Error Coin Collecting Through a Photo Contest
By Jimmy Krozel

Recently, the Willamette Coin Club (WCC) in Portland, OR, held our annual photo contest. This is one of my favorite events of the year, since it promotes coin collecting with an artistic thrust. Since I am very much an enthusiast of art as much as I am an enthusiast of numismatics, it is natural for me to think about how art and error coins can complement each other. This may seem like an odd match, but I’ve tried here to accomplish this goal.

More Than Meets The Eye
By Greg Bennick

Learn the minting process. I could have this entire article just be the retyping of those four words over and over again for an entire page and it would be a perfectly good use of space. When I was a kid, I read everything I could about the minting process, from raw metal to finished coins. I learned every step of what happens when a coin is made, and most (I could never claim to know all) of what mishaps might occur along the way. Throughout my collecting life that knowledge has proven to be invaluable.

Laminated Planchet Error
By Ken Potter

1917-S Lincoln cent and a 1949-S Jefferson nickel with Lamination Peels. Laminations are most commonly the result of contaminants, slag, occluded gas, improper alloy mix, etc., causing the metal to laminate as shown here. Laminations are very common on “War Nickels”.

Cuve’s Round Up 24
By Jason Cuvelier

Below is a an extreme die clash that I have been looking for many years to find. It’s not in the best shape, but it shows what is probably the strongest die clash from the US Mint. We have it listed as ADC-5c-2000P-02 on maddieclashes.com. The vast majority of the design elements have been clashed in the opposing die faces. You can see the opposing motto peaking behind the normal design elements throughout the obverse and reverse. Detail shots follow. Next is a coin I photographed a while ago that was at Angel Dee’s booth at the ANA. It is a beautiful 1970S Lincoln cent DDO-001.

Next are two no date (ND) 1974-1982 coper struck foldover Lincoln Cents from the E Raser collection and a Washington Golden Dollar Type 1 Counter Clash.
