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 Calagary 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.
Interesting fact
One interesting fact about this coin is that it was used during the Tang Dynasty, which was a period of significant cultural and economic growth in China. The coin's design features the Chinese character "yi" (乙) on one side and a square hole in the center of the other side, which was used to thread a string through for easy carrying. Despite being made of bronze, this coin was valued at a relatively low denomination, reflecting the Tang Dynasty's emphasis on promoting trade and commerce.
