拍品描述： 西藏乾隆五十八年乾隆宝藏五分银币。 罕见 发行，PCGS中少於10枚。设计细节深邃，币面些许磨损，毫不碍眼。有些锈蚀致得此评分，但瑕不掩瑜。上一枚我们於2018年经手，离当时已相隔一段时间，藏家入手版式稀少版别的绝佳机会。

CHINA. Tibet. 1/2 Tangka, Year 58 (1793/4). Chien-lung (Qianlong). PCGS Genuine--Environmental Damage, VF Details. L&M-638A; K-Unlisted; KM-C-66.1; WS-0198. An EXTREMELY RARE issue, with less than 10 having been certified by PCGS. The details of the design are strongly impressed, and very little technical wear is presented on the surfaces. Some encrustation and buildups likely account for the designation by PCGS, though these buildups are not obtrusive. Given that the last example of this type that we were able to locate at auction was offered in 2018, it may be quite some time before another example surfaces for the advanced collector to acquire.
