1950-S/D Washington Quarter Identification Guide

Documented Fact The 1950-S/D is a San Francisco Washington quarter with a final S mintmark punched over an earlier D. PCGS lists it separately from the 1950-D/S. ^{[1] [2]}

Quick Hunt

1. Confirm the 1950 date and dominant S mintmark on the reverse.
2. Inspect within and around the S for straight and curved remnants belonging to a D.
3. Match the whole S/D pattern to certified close-ups.
4. Reject the opposite D/S variety, ordinary S/S repunching, and damage.

Primary Diagnostic

Punch order controls the name: the visible final mintmark is S, with D remnants beneath it. Both identity and relative position must match certified examples.

What It Is Not

A 1950-D/S has the opposite final mintmark. Random notches, strike doubling, or an S/S do not establish S/D.

Authentication Caution

Use stable magnification and several lighting angles. Match the complete marker relationship to certified examples, do not clean the coin, and obtain professional attribution before paying a substantial premium.
