Li vs Seal Calligraphy script, Song dynasty 3 Chinese coins;Xuan He Tong Bao;Zheng He Tong Bao;Age; Song dynasty 960-1279;Size: 22 - 25 mm;Weight: 3.0 - 4.5 g;Seal script (pinyin: zhuànsh) is an ancient style of Chinese calligraphy. It evolved organically out of the Zhou dynasty script, arising in the Warring State of Qin. The Qin variant of seal script became the standard and was adopted as the formal script for all of China in the Qin dynasty, and was still widely used for decorative engraving and seals (name chops, or signets) in the Han dynasty. The literal translation of its Chinese name (zhuànsh) is decorative engraving script, because by the time this name was coined in the Han dynasty, its role had been reduced to ceremonial inscriptions rather than as a standardized script.
