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 symbol of Islam. This is significant because it suggests that the Empire of China, which was predominantly Buddhist, had trade and cultural exchange with Islamic regions during this time period. This coin, minted during the reign of Emperor Kaiyuan, was likely used for everyday transactions and circulated widely throughout the empire, highlighting the diversity and inclusivity of the Tang Dynasty.
