1899-O Morgan Silver Dollar. VAM-4. Top 100 Variety. Micro O. MS-63 (PCGS). CAC. A bright, brilliant and beautiful example with quality that is difficult to surpass for this popular Top 100 Morgan dollar VAM variety. Striking detail is sharp, luster is full, and the surfaces are minimally marked at the assigned grade level. Two die pairings comprise this variety with VAM-4, offered here, attributable by the normal placement of the date. On VAM-6 examples the digit 1 in the date is closer to Libertys neckline with its right base of the center of a dentil. Michael S. Fey and Jeff Oxman (1997) observe that the 1899-O Micro O is, "Extremely scarce in BU, with less than a dozen uncirculated specimens known for both VAMs combined." The intervening years since publication of their reference has increased the Mint State population somewhat, but not to an extent that reduces the rarity of this variety relative to collector demand. PCGS# 87260. NGC ID: 256C. PCGS Population (both VAM-4 and VAM-6 attributions): 14; 14 finer (MS-66 finest).CAC Population: 2; 6.
