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!

My Last Coin Show
by Christopher B

The last weekend in August, just a few weeks after my birthday, I found myself browsing an assortment of tables and dealers on the most exciting day of the year. I was at the Ohio State Coin Show, the largest show around the area, and the biggest I have been to yet. Being two-and-a-half hours from my house, it took quite the persuading to get my parents to drive me there. With visions of all of the coins and people I would see, those two hours felt like days….

Two Errors for the Price of One? A Russian 2 Kopek
By Mark Benvenuto

I confess that as time has gone on, I have looked more intently for coins that I might classify as errors when I look through any dealer’s stock. Some pieces that I might have passed by I take a renewed interest in if there is something not quite right….

Dual Country – Double Denomination Panama 1c Double Struck on U.S. Lincoln Cent
By CW4 Jeff Ylitalo, USA (ret)

This major mint error is a lustrous 1982 Panama 1 Centesimo Double Struck on a previously struck United States cu 1982 Lincoln Cent. The coin rotated 90 degrees CCW after the first strike with a beautiful second strike that is 30% off-center.

Treasures Among Treasure
“It is not the word that commands the story; it’s the ear”
by Dr. Ron Brown

1984 DDO-001 (FS-101) Doubling is ear outline below the primary ear detail.

I think some Lincoln cent collectors are going to be surprised by the number and dates of Lincoln Double Dies that show doubling of the ear. As best I could, I have included here a current list that I compiled and it is not intended to be comprehensive.

Discrepancy Found in Long-Used Standard for Mint Mark Style Listings San Francisco Mint Mark Punch Used in the 40’s and 50’s Reemerged Decades Later.
by Will Brooks

Figure 1. A 1942 S Mint mark (left) and a 1974 S Mint mark (right).

The long-used industry standard for identifying the different Mint Mark styles used over the years was established by Dr. James Wiles and can be seen at his varietyvista website, www.varietyvista.com. In the November, 2018 issue of Coin World Monthly, I explained the features of the San Francisco Mint mark style listed by Dr. Wiles as MMS-009 (Mint Mark Style-009). According to Wiles’ listings, this punch came into service in 1974 and was used until 1979. This was a bad-looking punch which had a series of defects. Assuming that this punch was brought into service in 1974, I concluded in that article that this punch must have been made with those defects and that they were not the result of the punch’s deterioration from over-use. I have since discovered that this conclusion was incorrect.

Examples of Off Metal Errors on U.S. and Philippine Coinage
By Benjamin C. Simpson, YN, and John L. Simpson

1961 Jefferson Nickel

Off metal or wrong planchet errors occur when a planchet for one coin is struck by a press intended for a different denomination. They are among the most interesting and prized errors and can occur in numerous ways. Between 1855 and 1984, the United States Mint produced coins for 43 different countries ranging from Australia to Venezuela (interestingly, official sanction did not come until The Mint Act of 1874). Sometimes these foreign planchets were struck by American dies. This article will focus on wrong planchet errors created during the U.S. production of Philippine coinage.

The national Money show had many highlights from the exciting interaction of new collectors interested in CONECA and the interaction with the many who already are members. It was and is an honor to represent!

Can Intent Define an Error Coin
by Al Raddi

Figure 1. Obverse of the Portugal 1999 100-escudo coin with the name of the issuing country spelled incorrectly in the legend PORTUGUSA

A simple definition of an error coin is: a coin that was manufactured incorrectly. However, what if a coin was manufactured correctly but designed incorrectly – is it an error coin?

Cuve’s Error-Variety-Clash Round Up 9
By Jason Cuvelier

Never assume, my mentor in graduate school would tell me. I try not to. On my scope appeared to be a die clash we had listed with a counter clash listed as CCL(T1)-50c-1983P-01. It was matching the photos, but there seemed to be additional clashing.
