1911-D $2 1/2 MS65 NGC. The Denver Mint found its production
capacity pulled in many different directions in 1911.
Double eagles were in high demand, and the Colorado
facility struck its first cents, amounting to an eight-figure
sum, in that year. Dimes, too, rolled off the presses
in quantity. For the other denominations, however, there
was comparatively little demand. Each of the lower-value
gold coins for that date and mint are among the keys
to their respective series, with the 1911-D quarter
eagle as the best-known example of this phenomenon.
The 1911-D's status has been documented thoroughly for
decades. Perhaps the most illustrative and eloquent
commentary on the date came from Paul M. Green, who
discussed it in a Numismatic News article dated September
17, 1996. He wrote that its mintage made it " ...
far and away the lowest production date of the type.
It had not become any more common over the years. It
always has, and always will be the key date in the Indian
Head quarter eagle set."
