2010 was a slow year for doubled die reports, with only four
listings in my files for that date.
All are on the obverse of Lincoln cents and all would be
considered minor doubled die varieties. It was starting to look like
2011 would be a carbon copy of last year, but that changed quickly
with the recent report of two significant doubled dies for the 2011
The first is a 2011 Lincoln, Doubled Die Obverse cent reported by
Joseph Koelling. If that name sounds familiar, it is because Mr.
Koelling is an avid searcher of coins for die varieties and has made
several significant finds over the past few years that we have
featured in this column.
Koelling’s 2011 cent shows unusually strong extra thickness to the
date, the letters of liberty, and the letters of in god we trust. In
addition to the extra thickness, strong notching shows on the lower 2
in the date, both 1s in the date and the ty of liberty. I have this
one listed in my files as 2011 1¢ WDDO-002.
It quickly created a stir in the die variety hobby and made its
way to all of the leading die variety attributers. Die variety
specialist Billy G. Crawford listed the variety as 2011 1¢ CDDO-003.
Bob Piazza listed the variety as 2011P-1DO-004 for the Coppercoins.com
website and James Wiles listed it as 2011 1¢ 1-O-VI for the CONECA
Doubled Die Files, sponsored by the Combined Organizations of
Numismatic Error Collectors of America.
No sooner had this variety made the rounds than Crawford created a
stir of his own with the discovery of the first known doubled die on
the reverse of a Lincoln, Union Shield cent. His 2011 cent shows very
strong extra thickness on one cent and united states of america with
the easiest place to spot the variety being the designer’s initials lb
I have this one listed as 2011 1¢ WDDR-001 while Crawford lists it
as CDDR-001. Coppercoins.com lists it as 2011P-1DR-001 while CONECA
has it down as 1-R-VI.
I can’t wait to see what else Coin World readers find for
2011, since we are only a little more than halfway through the year.
