Very interesting. The back of this Anhwei banknote specifically mentions that any vendors who rejected this note should be held accounted for by the government. Most of the Chinese papermoney before the 1900s were exchangable for copper cash coins rather than silver, so I think they really wanted the local people to know these new banknotes were equivalent to silver coins.
Some other provincial governmental or private banks did that in the same time period as well:
Kiangnan, Yu Ning Imperial Bank, 1905, 1 dollar

http://www.banknote.ws/COLLECTION/c...CINS2385.htmA private bank called "Wan Yi Chuan" in Tientsin, 1903. Just in case people didn't understand how valuable 10 dollars is, this banknote depicted 10 silver dragons in a stack!
