拍品描述： 民國二十五年孫中山像中圓銀樣幣。舊金山造幣廠。於1935年以后，美国再次迫使中国继续打铸银币之时，在旧金山所铸。比起其他孙中山钱币尺寸较小。正面有引人入胜的轻浅薰衣草色包浆，光泽流转。对於鐘情孙中山铸币的藏家而言，此為千载难逢的入手良机，PCGS及NGC中仅六枚曾经评鑑，此枚是最高分的孤品，冠绝群雄。CHINA. Silver 1/2 Dollar (50 Cents) Pattern, Year 25 (1936). San Francisco Mint. NGC MS-64.L&M-114; K-635; KM-Pn169; WS-0153; Wenchao-927 (rarity: ★★★). Struck in San Francisco after the U.S. government forced Republican China to continue striking silver coinage after 1935, this IMMENSELY RARE minor denomination dazzles with lustrous brilliance and a light lilac nature to the toning. For the advanced collector of the Sun Yat-sen series, this smaller pattern undoubtedly presents a wondrous opportunity and one over which a spirited battle will likely be fought. Across both major services, just six have been seen of the type, with this example being the sole finest.
