This is a historically significant Chinese silver coin from the Republic of China era, specifically the 'Year 6 of the Republic' (1917) issue featuring President Yuan Shikai's profile—commonly known as the 'Yuan Datou' (Big Head Yuan). The obverse displays Yuan Shikai in right-facing profile with the inscription '中华民国六年' (Republic of China, Year 6), while the reverse features the denomination '壹圆' (One Yuan) encircled by a wreath of wheat and rice stalks, symbolizing agricultural prosperity. Though labeled 'copper-plated silver' in the image text, authentic specimens are typically 89% silver alloy; this may indicate a modern replica or restrike. With a diameter of 3.9 cm, thickness of 0.28 cm, and weight of 27 g, it reflects standard mint specifications of the era. Highly valued by numismatists for its historical importance, craftsmanship, and symbolic role in early 20th-century Chinese monetary reform. Ideal for collectors, historians, or as a cultural artifact display piece—not wearable fashion or functional currency today.
