1920

Philadelphia struck 6,372,000 Walking Liberty halves in 1920, a meaningful rebound from the 962,000-piece 1919 figure and a return to mid-tier production volume for the series. The date carries no mintmark, since branch identifiers were reserved for Denver and San Francisco issues with mintmarks placed on the reverse at the lower-left rock beneath the eagle's tail. After the demanding 1919 trio, the 1920 Philadelphia feels comparatively accessible in lower grades, although it shares the strike weaknesses common to all early Walkers and presents real difficulty in choice mint state. Collectors often use this date as a breathing point in a date set before encountering the 1921 keys.

Strike characteristics on 1920 Philadelphia Walkers follow the established series pattern. Liberty's left hand and skirt thumb area come weak on most examples, and the eagle's central breast feathers and talon gripping the perch are softly defined on the majority of survivors. Surfaces typically display the satiny luster expected of 1920 Philadelphia silver, although bagmarks from rapid commercial use are common. Authentication begins with confirming the 12.50 g weight and 30.61 mm diameter and inspecting the reeded edge for sharp, unfiled definition. Verify the absence of any mintmark on the reverse, since the host coin for some added-D and added-S forgeries comes from common Philadelphia dates of this period. Die markers on genuine 1920-P examples include light radial flow lines on late-state dies and consistent rim definition. Counterfeit detection benefits from comparison of overall design relief, which tends to flatten on cast or struck fakes.

Professional Coin Grading Service (PCGS) and Numismatic Guaranty Company (NGC) population reports show the 1920 Philadelphia is available through MS64 with patience, while MS65 examples thin out and MS66 coins become condition rarities. Full Strike examples at every grade level carry premiums. Type collectors often source no-mintmark slots from this date when 1918 examples prove elusive, and date-set builders compare it to the 1920-D and 1920-S for relative grade availability.
