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!

Some Monster Standing Liberty Quarter Errors
By Robert H. Knauss

I have been collecting Standing Liberty Quarter errors for twenty years and have written pretty extensively on that subject. During that time, I have run across some amazing major errors and wanted to share a few of my favorites with you.

Treasures Among Treasure
Ostensibly a Misplaced Mint Mark on the Reverse of a 1962 Proof Franklin Half
by Dr. Ron Brown

Note the D’s location SE of the letter W in STOW

There are some interesting varieties in the Franklin series but none more so than the unusual anomalous “D” on the reverse of the 1962 Proof Franklin Half Dollar, FS-901. Where this supposed “D” comes from is anyone guess.

Another Look at a Key Feature of the 1883 O VAM 33
By John Roberts

A bank of lathes in the Philadelphia Mint as pictured in the Annual Report of the Director of the Mint in 1902. These could be used both for shaping the edges of medals and turning off displaced metal from dies between hubbing blows. Either operation would produce numerous small shards of metal in this room.

In my typical work day I examine a significant number of Morgan Dollar varieties. Most of these pieces have become well-traveled ground for me, but there are some that capture my attention and warrant a closer look. These may become subjects of my monthly column About VAMs that is published in Coin World. On rare occasion, I’ll encounter something that inspires a far more detailed investigation.

VAM 2A Earring Crown Peace Dollar
By John Cava

1922-P VAM 2A. Often referred to as the Earring variety.

It’s often said that patience is a virtue and I am normally a virtuous man. But the other day I gave up waiting and pulled the trigger on one of the “Crown Jewels” of the Top 50 Peace Dollar VAMs. As you may recall, the Top 50 Peace Dollar VAMs are just a small sub-group of the 100’s of identified Peace Dollar VAMs. These 50 are singled out because they are visible to the naked eye, well at least younger eyes.

Stay safe everyone.

Paper Money Errors: The Offset Printing
By Benjamin C. Simpson, YN

This series 1977 $10 note exhibits a partial offset

Few paper money mistakes are more captivating than the offset. It is easy to understand why this error type is so popular; their impressive appearance and affordability make them a perfect entry point for currency collectors.

Modern Lincoln Cents Plagued by Striations
Commonplace but Puzzling Planchet Error Explained
by Will Brooks
edited by Mike Diamond

Extreme example of a striated planchet found among many minor examples by Steve Wilhite of Arizona in a solid date 2018D Loomis original bank-wrapped roll.

Ever since the Mint began striking Lincoln cents on copper-plated zinc planchets, the occasional cent with thin parallel striations would turn up. Recently, the frequency and severity of this phenomenon has gone up dramatically.

A Bit of CONECA History
By Michael S. Fey, Ph.D.
Attributor of Silver Dollars for CONECA

I bought a collection and found this piece of CONECA history in the lot. It will be of interest to readers who have a long history with our association.

Distinguishing a Folded Over Rim Fin from a Rim Cud on United States Coins
by Pete Apple

In order to determine whether a feature is a rim cud or a folded over rim fin, I try to envision the die which produced the feature. In many instances, we will find a feature which covers anywhere from 45º to 100º on the rim around the circumference of the coin.

In the photo above, the length of the cud exceeds ≈ ½ the radius of the coin and is no longer a rim cud because the break has encroached into the area of the field.

Cuve’s Error-Variety-Clash Round Up 10
By Jason Cuvelier

Chile 2001 5 peso DDO

You have to wonder about what exactly happens in some Mints around the world were you can have some of these weird mishaps causing crazy die errors, at the same time, from an error and variety numismatic standpoint, it is rather cool to be able to study these mistakes.
