Historical Context: The Kaiyuan Tongbao, meaning "Circulating Treasure of the Opening Epoch," was introduced in 621 AD by Emperor Gaozu, founder of the Tang Dynasty (618-907 AD). This revolutionary coinage replaced the archaic wuzhu system, establishing a new standard of 10 cash to one tael. Its standardized weight and elegant inscription marked a significant numismatic reform that profoundly influenced Chinese coinage for over five centuries, defining the 'yuanbao' and 'tongbao' nomenclature. The Tang era itself was a golden age of cultural and economic prosperity.
Artistry: The design of the Kaiyuan Tongbao is renowned for its calligraphic excellence, traditionally attributed to the master Ouyang Xun. Executed in a powerful and balanced regular script (kaishu), the four characters (開元通寶) are arranged clockwise around the central square hole. This specific variety is distinguished by a small dot, often found above the top character "開" or elsewhere, which served as a potential mint mark, assay indicator, or numerical denotation. This aesthetic set a benchmark for subsequent Chinese cash coin designs.
Technical/Grading: This bronze 1 Cash coin, measuring approximately 25 mm and weighing 3.45 grams, exhibits typical casting qualities of the early Tang period. Key elements for evaluation include the sharpness and clarity of the calligraphic characters and the definition of both inner and outer rims. A well-formed central square hole is also desirable. While early issues often display superior strike quality, casting variations are common. The distinguishing dot, crucial for variety identification (Hartill#14.1m-t), should be clearly visible, contributing to the coin's overall grade.
