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.
Interesting fact
One interesting fact about this coin is that it was produced during the Kaiyuan era of the Tang dynasty, which was a time of great economic and cultural prosperity in China. The Kaiyuan Tongbao coinage was introduced by Emperor Wuzong in 841 CE and was used until 907 CE. These coins were made of bronze and had a standardized weight and size, which made them easily recognizable and trustworthy for trade. The 1 Cash coin weighed 3.29 grams and was a widely used denomination during that time.
