拍品描述： China - Provincial. TAIWAN: Tao Kuang, 1820-1850, AR dollar, Jiayi Mint, ND (1838-50), Cr-25-3, L&M-319, K-1b, so-called "Old Man Dollar", God of Longevity with kùpíng qi èr (treasury standard 7 [mace] 2 [candareens]) below, dàoguang nián zhù (cast during reign of Daoguang) to left, zú wényín bing (pure [fine] silver coin) to right // large tripod cauldron (ding) with a swastika on each side, Manchu legend tai wan above and below, kyagi ku on the sides, two rectangular official stamps of approval at reverse 7h, several merchants chopmarks on both sides, PCGS graded VF details (chopmark). This type is said to have been issued in the 17th year of Daoguangs reign by the local government in order to pay troops to suppress a rebellion led by Zhang Wen. Its high purity (ca. 98%) and greater silver content than contemporary Western crowns made it a popular currency, as it is often found with numerous chopmarks. But this also led to many examples being melted down, which further contributes to its great scarcity today.
