In tiande 2 (944), Wang Yanzheng minted Tiande tongbao large iron coins, at a face value of 100, but none of them has survived. A Tiande zhongbao bronze coin has been preserved. It is covered with iron rust, and its reverse bears the character yin, because when Wang Yanzheng was proclaimed Emperor in Jianzhou, he changed his state's name to Yin, and he only restored the state's original name of Min in the third year after that. These Min coins are all extremely rare.

Seems to be a latest imitation.

This one is a recent fake of the rare coin which comes in three varieties, of which this clerkly writing of Bao variety is the rarest.
