1917-S Walking Liberty Half Dollar. Obverse Mintmark. MS-64 (PCGS). CAC. CMQ.This is a lovely example of a leading condition rarity among Walking Liberty half dollars. Both sides are dusted with lovely champagne-gold iridescence that is boldest around the reverse periphery. The strike is impressively sharp with full detail to all but a few isolated design features. Satiny with the characteristic stippled texture of an early date half dollar of this type, the surfaces are exceptionally well preserved and worthy of the Choice Mint State grade.<p>The 1917-S keeps company with eight others in the Walking Liberty series that had mintages of fewer than one million pieces. Only 952,000 half dollars were struck at the San Francisco Mint in 1917 with the mintmark on the obverse, in fact, and for many years this was considered one of the key dates to the series. Today, however, the 1917-S Obverse Mintmark is known to be fairly available in grades from About Uncirculated to MS-63. In MS-64 and MS-65 it remains rare while the MS-64 offered here is truly impressive for the grade, as confirmed by both CAC and CMQ.PCGS# 6572. NGC ID: 24PT.
