ONECA is the 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. CONECA publishes an educational magazine,
TheErrorscope, which is printed and mailed to
members bimonthly. Visit the CONECA
web site at
he CONECA die varieties numbering system
is proprietary to the Combined Organizations of
Numismatic Error Collectors of America and is
used under license issued by CONECA.
These variety master listings are offered as a
work in progress.
They should not be considered as permanent listings unless they have had prior
publication with an accompanying photo for identification.
Furthermore
population numbers
represent only the coins that I have seen, thus they should be
considered as minimum known rather than maximum known.
