1927-D Standing Liberty Quarter
The 1927-D Standing Liberty quarter is a significant challenge to specialists of the series. With a total of just 976,000 coins produced, it has the third lowest mintage of the entire series after the rare 1916 and the 1927-S.
The example to the left was sold by Stack's Bowers Galleries in the March 2013 Baltimore Auction, where it realized $8,812.
