1852-O Liberty Seated Dime. Fortin-101. Rarity-4. MS-64 (NGC).The pearlescent underlying surfaces of this near-Gem are draped in a delightful sapphire and olive iridescence across each side. Uniformly bold devices project handsomely from smooth and untroubled fields, delivering a technical merit to match the strong eye appeal throughout. The mintage of the 1852-O dime is 430,000 pieces, many of which were melted as the Gold Rush in California upset the delicate balance between gold and silver in the world market.
