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 features a crescent shape on one side, which is a unique design element for a Chinese coin. The crescent shape is believed to represent the Islamic influence on the Tang Dynasty, which ruled China during the time this coin was minted. This coin is a rare example of how cultural exchange and religious diversity were reflected in the currency of ancient China.
