This is a 20-cent nickel coin first issued in the 25th year of the Republic of China (AD 1936) by the Central Mint under the Nationalist Government, as part of a currency reform aimed at implementing a decimal monetary system.
The obverse of the coin features a left-facing portrait of Sun Yat-sen. The upper edge is inscribed with the issuance year, “The 31st Year of the Republic of China” (中華民國三十一年). The outer rim is adorned with a key-pattern design, commonly found on ancient Chinese bronzeware.
The reverse of the coin features a key-pattern border similar to the obverse. At the centre is an image of a spade money, a form of currency used during the Spring and Autumn and Warring States periods, which was also adopted by the Nationalist Government as the emblem of the Ministry of Finance. Inside the spade coin is the character “財” (finance) in an oracle bone script-inspired style. On either side of the spade coin, the denomination “廿分” (20 cents) is inscribed in Chinese characters.
In AD 1936, shortly after the Central Mint was ordered by the government to produce decimal-based nickel coins, its location in Shanghai faced attacks from the Japanese military the following year. Beginning in late summer of AD 1937, the mint’s machinery was dismantled—some were hidden on-site, while the majority were gradually relocated to inland cities such as Wuchang, Guilin, Chongqing, Lanzhou, and Chengdu. This strategic relocation aimed to ensure the continued issuance of currency during wartime.
Due to the escalating Second Sino-Japanese War, the supply of nickel became increasingly scarce and its price rose sharply. In response, starting in AD 1940, the Ministry of Finance mandated a new coinage composition, replacing pure nickel with an alloy consisting of 18% nickel, 27% zinc, and 55% copper.
