1889-S Morgan Silver Dollar. MS-66 (PCGS). CAC. On this delightful premium Gem, both sides are sharply struck with brilliant mint frost. The 1889-S is a scarcer Morgan silver dollar issue with a mintage of just 700,000 pieces, survivors of which are typically found in grades below MS-65. At the Gem level it becomes conditionally rare and is considerably more elusive at MS-66. From the Larry H. Miller Collection. Ex Cajun Collection. From the Larry H. Miller Collection.
