1920-S Walking Liberty Half Dollar. MS-64+ (PCGS). CAC. Lightly toned and about average in strike detail at the obverse center. Precious few 1920-S Walking Liberty halves show even half of the detail that characterizes both sides of this frosty specimen. There are no reportable contact marks on either side and the soft golden toning is seen mostly on the reverse while the obverse remains mostly brilliant. With the change to 1920-dated dies, the mint again adjusted the design of the Walking Liberty half dollar. Libertys cap has been redesigned with more grooves at the back and a larger fold at the top. Below, the ground line from date to sun has been given a sharp raised edge. Finally, the outer edge of the flag curl by the knee has had a raised border added.
