廣東雙毫, 20-Cents in Silver , Kwang-Tung Province, China Republic Year 8 (1919). "After the revolution the Canton Mint switched its production of ‘small coin’ to a Republican design copied from the Straits Settlements coins. Minting of 20- and 10-cents started at 780 fine, but the quality was systematically debased for two years during WWI due to the high price of silver." 中華民國八年，廣東省雙毫銀幣。 “廣東造幣廠 民國成立後, 仿照海峽殖民地硬幣圖案, 鑄造帶共和色彩之弍亳及壹毫銀幣。最初成色為780, 但第一次世界大戰期間因銀價高昂, 有兩年之銀幣成色刻意減低。”
