| Obverse description | Round cast bronze coin with a central square hole, struck in the clerical script (lishu) style. Four Chinese characters are arranged in cruciform fashion around the central perforation, reading top-to-bottom and right-to-left: 得 (top), 壹 (right), 元 (bottom), 寶 (left), rendering the inscription 'Deyi Yuanbao' (得壹元寶). The characters are bold and well-defined, set within a raised inner rim bordering the square hole, and enclosed by a raised outer rim. The flat field between the characters shows the typical unadorned surface of Tang-era rebel coinage. |

| Additional information |
The Great Yan State was a rebel polity proclaimed by Shi Siming after he recaptured Luoyang from Tang forces in 759, following the An Lushan Rebellion that had already shattered Tang fiscal infrastructure. The Deyi Yuanbao was issued as political currency in the most literal sense — a declaration of legitimacy pressed in bronze at a moment when two rival courts were simultaneously striking coin.
Shi Siming was assassinated by his own son, Shi Chaoyi, in 761, collapsing the rebellion's momentum entirely. The regime's brief window means surviving examples derive from a narrow production span of roughly two years.
