Comments

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.
