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 January/February 2020 color issue of Errorscope
has been added to the members only section of the site.

Articles in the January/February 2020 Issue of CONECA’s ErrorScope include:

Tiny, Copper, and As Beat Up As Possible?
By Mark Benvenuto

For those of us who avidly look for error coins, what are now considered medieval coins can be both a blessing and a curse.

Clipped/Incomplete Planchet Mint Error
Jefferson Nickels
By Denny Polly

One of my favorite mint error coin types is “Struck on Clipped Planchet Mint Error Coins”. These are also more recently being called “Struck on Incomplete Planchet Mint Errors” and that is the more accurate technical description.

1964-D Jefferson 5 Clips Including Two Sets of Overlapping Clips


PAN Show’s VAM-4 Find

The last two issues of ErrorScope have included articles by Mr. John Cava about a pair of Peace Dollar VAMS in his collection. Since I am also a Peace Dollar collector, I decided to take up Mr. Cava’s challenge and see if I could find VAMs in my own modest collection.

Treasures Among Treasure
1968 D Lincoln Cent – The Rare Doubled Die Reverse
by Dr. Ron Brown

I was recently asked why I title my articles “Treasures among Treasure”. As you likely already surmised, I like describing coins I have attributed or own (with very rare exception) often found from within my coin accumulations – if you will, a treasure hunt within my already accumulated treasures – thus, “Treasures among Treasure”. In so doing, I hope to encourage others to make sure that they too have examined their coins for varieties and hopefully find a treasure.

Cuve’s Error-Variety-Clash Round Up 7
By Jason Cuvelier

As much as you would expect a state sponsored Mint to employ reasonable quality control measures, you have to love when they don not and things go wrong in a dramatic way. In the past I have been showcasing some nice doubled dies from Brazil, India, Columbia the U.S. and Britain. I have recently been able to track down a number of nicer doubled dies from Malaysia and will be periodically showcasing some of them.

I am happy to include another member find from CONECA member Zeppo Young who sent in a
2016 North Dakota ATB Quarter. I was able to add it the files on MadDieClashes.com as 2016 ADC-25c-2016-01-RO (or ADC-2016-01 shortened). On the reverse we RTY clashed in the stream as well as OD above the saddle behind Roosevelt.

Below is another submission, this is from CONECA member Robert Umbarger, which is an 1883O
Morgan clashed dies that I identified as being Vam-14.

Lastly this is issue I have acquired the plate coin for ADC-1c-1960D-01(LD) which also happens to
have RPM-099 in something closer to MDS. There is no current stage information in the CONECA files for this stage, coupled with a hit on the mintmark, it was not easy to verify the RPM attribution. Coupled with the time to make an overlay to check for MM position, it took some additional time to light it in a way that I could compare details and convince myself that the attribution was indeed correct. Detail shots of the RPM and die clashing are below.
