I'm looking for help completing the census of shattered dies and die progressions for the dies from the Philadelphia Mint (2007). With the help of BJ Neff, John Sullivan and Fred Weinberg, there are 10 documented dies and progressions with attribution numbers. We are aware of more, but need high quality images that can be compared with existing pieces. Please email me at george@stonejungle.com or BJ at cudsoncoins@aol.com. For a look at what has been catalogued, visit http://cuds-on-coins.com/shattered-dies-on-u-s-dimes/

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 us our main site Here
