Your coin is a fake.
It combines the reverse of the Manchu mint
"Boo-chiowan" with the obverse of a cash coin struck by the
Taiping Rebellion (1851-64); with the characters "太平通寶" (Tai-ping Tong Bao).
This is an impossible combination made by a massively ignorant forger; the Taiping, a rebellion against the Manchu Qing Dynasty would not have used the official mints, or included Manchu characters on their coins! Plus the character "平" looks far too modern for the time, compared to the second link above; and the way it looks just screams modern replica.
Welcome to Numista, by the way!
