1920-S Walking Liberty Half Dollar. MS-63 (PCGS).A beautifully toned example of this conditionally challenging early date Walking Liberty half dollar issue. The obverse exhibits a bold crescent of steel-blue along the left border, the balance of this side dressed in lighter reddish-gold. The reverse is brilliant apart from a splash of reddish-gold along the left periphery. Fully lustrous and solidly in the Choice Mint State category. After producing only 1,552,000 half dollars in 1919, the San Francisco Mint increased its output for this denomination to 4,624,000 coins in 1920. The 1920-S is among the more difficult Walking Liberty half dollars to locate in Mint State. In terms of total number of Uncirculated coins extant, in fact, the 1920-S ranks 10th in rarity among the 65 circulation strike issues of this type. This is a superior quality coin for the assigned grade that would be an excellent choice for an advanced collection.
