It's a Chinese cash coin, I dint know much more about it, I'm not very knowledgeable on that specific type. Someone here will be able to tell you more though
Hmm I'm am stumped so far. Checked http://tjbuggey.ancients.info/Chinese.html and could not find an exact match. Some symbols matched a few different coins but nothing exactly the same. There are gaps in this list.
I think I found it Emperor HSUAN TSUNG AD 1821-1850 Reign title: TAO-KUANG, AD 1821-1850 S-1512, "BOO CIOWAN" (Board of Revenue mint). The Manchu mint name translates to Pao-Ch'uan, or "The Fountain head of the Currency". F $2.00 VF $2.50
