1920-S Walking Liberty Half Dollar. MS-61 (NGC).，This golden-gray example offers emerging detail to the high points, especially on the reverse.

In fact, Jeff Ambio in his 2008 book, <em>Collecting & Investing Strategies for Walking Liberty Half Dollars, </em>ranked it among the ten rarest Walking Liberty issues in terms of total number of Uncirculated coins known, a status which still stands today in 2017.，PCGS# 6582. NGC ID: 24R5.，，From the Domino Collection II.
