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 coin's design features the Chinese character "zi" (子), which means "son" or "child," and was likely used to signify the coin's value as a small denomination. Despite its small size, this coin is a significant artifact of Chinese history and a valuable collector's item for numismatists today.
