拍品描述： 孙中山像开国纪念壹圆银币。南京造币厂。上五星，耳下有点。颇罕见的开国纪念版。孙中山耳下及下颚后有点，非同寻常。中度磨损。工具痕迹位于正面底板，但有深色柜藏包浆稍微掩盖。名扬四方的版别，必定能成为场上焦点。(t) CHINA. Dollar, ND (1912). Nanking Mint. PCGS Genuine--Tooled, EF Details.L&M-48A; K-600B; KM-Y-318.1; cf. WS-0158 (for regular issue; dot variant not recognized, though the plated example for the type features the dot). High five-pointed stars variety, with dot below ear. A rather <strong>RARE</strong> Memento Dollar variant. The unusual dot just below Sun Yat-sens ear and behind his jaw is quite visible on this example despite some moderate wear. The noted tooling appears across the obverse fields, though this drawback is subdued somewhat by the coins deep cabinet tone. An intriguing and well-provenanced piece that is likely to attract interest.Ex: Irving Goodman Collection.<p><p>Ex: Superior Galleries; 06/1991, Lot # 850 (with ticket).
