Comment

The reverse design depicts "The Flag of Iron Blood and Eighteen Stars", better known as the "Wuhan Flag", with the eighteen dots representing the eighteen provinces involved in the uprising. This revolution was the one that lead to the overthrow of the Qing dynasty and the founding of the Republic of China.

Qing authorities considered these coins to be an unauthorized illegal issues, and by law, anyone found carrying such pieces were subject to execution, and any examples falling into the Qing authorities' pocessions were to be destroyed. Very few examples are known to have survived, with most references suggesting only five are known (with two being in museums).

Confirmation is needed on whether the pictured example is a genuine coin from the revolution. Few examples are said to have survived, with a definitely-genuine example having waves in the background of the reverse and not having an incuse star, like the pictured example has. As well, various examples of this type are known, contradicting the "only five are known" comment most sources suggest.
