拍品描述： 民國十七年孫中山像四川省造壹圓銀幣。所有中国钱币中数一数二的罕见版别。四川发行，神龙见首不见尾的版别。耿爱德在其《中国币图说汇考》称："其由何人下令、铸於何处均无史实可考据"。一面雕刻孙中山常服肖像，当时孙中山刚逝世不久；另一面可见嘉禾及""一圆""面值。打於尺寸较平常一圆硬币小的币坯，直径 37 毫米，重 25.5 克。耿爱德对其铸造提出两个可能性：是成都造币厰的样币，或是私人发行军阀版。观其构造不如成都造币厂其他作品精緻，更似是军阀版。不论来源自何处， 其罕见程度毋庸置疑。NGC 仅评鉴过两枚，另有一枚获评受损的同版於鲍德温拍卖公司 2014 年 Norman Jacobs 集藏拍卖中拍出。以上為记录中存世仅知的三枚。些许经手痕跡，铸打粗糙，但表面原始，未有损伤，仍然动人。柔和的油亮光泽犹存，弱打轻微，细节稍有磨损但依然可见。孙中山像附近的轻微擦痕无损品相。无论是中国币还是四川造币藏家均会怦然心动。是千载难逢的收藏良机，切勿错过。(t) CHINA. Szechuan. Dollar, Year 17 (1928). Uncertain Mint. NGC VF-25.L&M-Unlisted; K-792; KM-Y-474; WS-Unlisted; Wenchao-Unlisted; CCMC-SCR.1.6. One of the highest peaks of RARITY in the entire Chinese numismatic series, this Szechuan Provincial Dollar couples elusiveness and numismatic mystery. As recorded in Eduard Kanns Illustrated Catalog of Chinese Coins</em>: "nothing authentic is known about where, and at whose orders this coin was produced." Depicting an effigy of the recently deceased Sun Yat-Sen in his civilian clothing, with the other side featuring a wreath of rice and bean grains with the typical denominational characters for "ONE YUAN". Produced on a smaller than normal flan for Dollar-sized emissions, as the diameter is only 37 millimeters and the weight 25.5 grams. Kann suggests two possibilities for this pieces manufacture, either as a pattern striking from the Chengdu Mint or private "warlord" issue. The fabric of the example suggests a more likely origin as a warlord type, with a style that does not generally conform to other products from Chengdu. Whatever the case with its origins, it is immediately clear that this Dollar is of the UTMOST RARITY. The present specimen is one of only two on the NGC census, with another damaged example trading in a 2014 Baldwins Auction from the Norman Jacobs Collection. These three pieces account for every known example we were able to trace in our research.Despite seeing some handling and of a generally crude manufacture, a degree of charm is retained by the original and undamaged surfaces. Some soft glossiness remains, and despite a slightly weak strike, evident details yet remain with only a bit of technical wearing. A few scuffs near the bust of Sun Yat-Sen are noted, though these do little to dampen the piece. A specimen that should receive a plethora of attention from completionists seeking to finish the Szechuan series, or more generally for any collector of Chinese Dollars. An opportunity that should not be missed by any advanced collector of Chinese coinage.Ex: NC Collection.
