It is from the Qing Dynasty emperor Gao Zong (1736-1795), who had the period title of Qian Long. It was cast at one of the four branches of the Beijing Board of Revenue mint. I can't tell which branch due to the level of wear. From the fishhook-like shape of the right-hand character at the top, it looks to be from the latter part of Qianlong's reign, 1774-1795.
