01 · Overview

Why the Winged Liberty Head (Mercury) Dime matters

Adolph A. Weinman's Winged Liberty Head dime is popularly called the Mercury dime because Liberty's winged cap was mistaken for the Roman god's helmet. It was struck from 1916 through 1945 at Philadelphia, Denver, and San Francisco.

The series combines famous key dates, overdate varieties, strike-sensitive Full Bands designations, and heavily circulated issues. A census comparison must specify date, mint, variety, grade, and band designation.

02 · Design

Reading the design

Winged Liberty

Liberty's cheek, hair above the ear, wing feathers, and neck are primary focal areas. Strike softness and circulation friction must be distinguished.

Fasces and olive branch

The central horizontal fasces bands provide the basis for Full Bands designations.

04 · Grading population

How many have been certified at each grade

No static census copied here. Full grade-by-grade counts change and are not republished without the exact issue, service, strike, designation, source, and as-of date. Use the official tools below; verified figures for an individual Nucoins coin appear on that coin's listing.

Population reports count submissions certified by a grading service. They do not count every surviving coin, and a series-wide total is not a substitute for the exact date, mint, variety, strike, designation, and grade. Nucoins listings show the population in the listed grade and the number graded higher when those figures have been checked against an official report.

Population in grade
Coins recorded by that service for the exact issue and assigned grade.
Higher / finer
Coins recorded by the same service in numerically higher applicable grades.
Report date
The date the figure was checked; counts can change after submissions, resubmissions, and database updates.
A grading population is not a rarity estimate, a count of unique survivors, or a guarantee of value. Coins may be resubmitted, and economically common grades may be underrepresented because certification costs exceed the coin's value.Read how to use a population report.

The series in stages

  1. 01 · 1916–1921

    Opening and key dates

    The 1916-D and low-output 1921 issues define the early date set.

  2. 02 · 1923–1931

    Middle period

    Includes the low-mintage 1926-S and substantial variation in strike quality.

  3. 03 · 1934–1945

    Later production and varieties

    High-output wartime dates coexist with the 1942/1 and 1942/1-D overdates.

Notable issue checkpoints

Production figures describe coins struck, not coins surviving or certified. Linked issue records provide the context for each figure.

06 · Examination

What photographs should help you examine

01

Obverse

Cheek, hair, and wing

Separate flat strike at hair and wing from friction on the cheek and high points.

02

Reverse

Central bands

For a Full Bands claim, inspect uninterrupted separation and apply the grading service's terminology.

03

Edge / holder

Mintmark and variety

Check mintmark shape and position; overdates require die-level confirmation.

07 · Before buying

Questions the listing should answer

01

Date and mint are only the beginning

A mintage figure records production, not the number surviving in a particular grade. Distribution, melting, storage, bag handling, and later collector demand all affect availability. Compare the complete issue and condition before drawing conclusions from mintage alone.

02

Surface quality can separate coins in the same grade

Two coins with the same assigned grade can differ in luster, strike, marks, toning, and overall visual balance. Review the focal areas and protected fields appropriate to the design rather than treating the grade number as a complete description.

03

Verify attribution before paying for it

Mint mark, recognized variety, special finish, and holder designation should agree with the coin and its certification record. Do not assume that an undocumented nickname or seller description establishes a variety.
