Drescription: The Winged Liberty Head dime, commonly known as the Mercury dime, was produced by the US Mint from 1916 to 1945. Designed by Adolph A. Weinman, the 90% silver coin features a portrait of Liberty in a winged Phrygian cap (symbolizing freedom of thought) on the obverse and a fasces with an olive branch (symbolizing unity and peace) on the reverse.

Key Features and Design Details:

Obverse: Features a young Liberty facing left, wearing a winged cap. The word "LIBERTY" arcs above the head, with "IN GOD WE TRUST" at the lower left and the date at the bottom.

Reverse: Features a fasces (a bundle of rods) overlaid with an olive branch. The legend "UNITED STATES OF AMERICA" and "ONE DIME" surrounds the design, with "E PLURIBUS UNUM" to the right.

Designer Initials: Weinman’s initials ("AW") are located on the obverse, to the right of Liberty's neck.

Composition: 90% silver, 10% copper (0.07234 troy ounces of pure silver).

Mint Marks: Located on the reverse, to the left of the olive branch (D for Denver, S for San Francisco; no mark for Philadelphia).

Significant Varieties: The 1916-D (low mintage), 1921-P/D, and 1942/41-P/D overdates are highly sought after.

"Full Split Bands" (FSB): Specimens with fully separated horizontal bands on the reverse fasces are considered higher quality and more valuable.

The coin's nickname, "Mercury," arose from public confusion, as the wings suggested the Roman god Mercury rather than Liberty. The series was replaced by the Roosevelt dime in 1946.
