Our first two featured coins this month take us back to the era
(pre-1990) when the Mint mark was hand punched into the working die.
It typically took more than one tap of the mallet on the hand-held
punch to produce a satisfactory image of the Mint mark on the working die.
If the punch were moved at all between taps of the mallet, a
doubled, or sometimes tripled, Mint mark resulted. These varieties
came to be known as “repunched Mint marks” or RPMs.
Mark Joyner submitted a 1955-D Lincoln cent with a very nice doubled
Mint mark that would be described as a D/D South. I have this one
listed as 1955-D 1¢ WRPM-002.
The Combined Organizations of Numismatic Error Collectors of America
(CONECA) lists it as RPM #2 and Coppercoins lists the variety as 1955D-1MM-002.
A 1943-D Winged Liberty Head dime with a very nice doubled Mint mark
was submitted by John S. Gillilan. This one would be described as a
D/D North. It is new to my files and I now have it listed as 1943-D
10¢ WRPM-011. CONECA has it in its files as RPM #8.
Back on the doubled die front, a 1973 Lincoln cent with a very nice
doubled die obverse was submitted by Robert M. Pelletier. It is a
Class I doubled die variety with doubling showing on IN GOD WE TRUST,
LIBERTY, and the date. I have it listed as 1973 1¢ WDDO-001. While it
is not a new listing for my files, it is still a very nice find.
Every once in a great while, a doubled die on a non-U.S. coin will
find its way into my Inbox. I do not maintain a file for world coin
die varieties, as the U.S. coin die varieties keep me busy enough.
However, if doubled die on a non-U.S. coin is strong enough, I will
occasionally sneak it into this column, just to let Coin World readers
know that nice doubled dies are out there from countries outside the
So it is with a 2001 Brazil 10-centavo coin from Joseph Mitchell,
which shows strong doubling on the entire obverse.
