Comment
In late 841, it was decided to replace the 'Chang' of Huichang coins with actual mintmarks. These mintmarks are often difficult to read due to being hand-stamped into the moulds, resulting in a higher relief more prone to wear.Some, like Calgary Coins, assume the mintmark-less Kaiyuan pieces were not minted after 841, and that the mintmarked pieces were continued until the end of the Tang dynasty.
While the mintmark is Gui, it is unknown whether that is for Guiyang in Hunan or Guizhou in Guangxi.
Interesting fact
One interesting fact about this coin is that it was produced during the Kaiyuan Tongbao era, which was a period of great economic and cultural prosperity in China, marked by the development of paper currency, the invention of the woodblock printing press, and the flourishing of Buddhism.
