I found out a little bit about this coin. I emailed some pictures to a coin selling place out of canada. he said:
"The coin is Chinese, from the Ching Dynasty, and is specifically a coin of the Emperor Chen Lung who ruled from AD 1736 to 1796. The mint mark is for the Board of Revenue mint, which is one of the two principle mints in Beijing, and is the most common mint for these.
This is the most common Chinese cash coin, and with the amount of wear on it, it is of little monetary value."
so that is a bummer, i thought i found something worth a little money,lol.
