Thanks to the folks at ANACS, the strongest known obverse doubled die
has been identified for the U.S. Mint’s State quarter dollar program.
The variety was spotted on the obverse of a Proof 1999-S Pennsylvania
copper-nickel clad quarter dollar.
A strong Class IV spread shows on the letters of LIBERTY, UNITED
STATES OF AMERICA, QUARTER DOLLAR, and slightly on the letters of IN
GOD WE TRUST and the S Mint mark. Class IV doubled dies are noted for
having all of the doubling spread in the same direction, in this case
to the east-southeast.
Apparently the hub was also tilted (a Class VIII doubled die) during
the hubbing process, resulting in the strongest spread being on the
left side of the obverse and the spread decreasing as you move from
left to right across the obverse. The quickest pick up point for the
doubling is the word LIBERTY.
Upon spotting the variety, ANACS sent the coin to James Wiles, the
20th century die variety attributer for the Combined Organizations of
Numismatic Error Collectors of America, to see if it was a known variety.
Wiles contacted other die variety specialists to see if anyone had
it listed and all confirmed it was a new variety.
I indicated to Wiles a desire to see the coin so that I could add it
to my files and share it in this column, and the request was forwarded
to ANACS. A short time later the coin arrived in the mail, and I now
have the variety listed as 1999-S 25¢ Pr PA WDDO-001.
The fact that it is an exceptionally strong doubled die is one
thing, but now you get to throw in the rarity factor. The average life
of a Proof quarter dollar working die is just 1,500 coins. That means
that it is unlikely that more than 1,500 examples on this variety
exist. Good luck finding one!
Topping things off for this month is a 2007-P Wyoming quarter dollar
with a doubled die reverse that shows doubling of the saddle horn that
is typical for this design. It was submitted by Coin World
reader William Dorvall and is listed as 2007-P 25¢ WY WDDR-074.
