Very nice. It’s a bronze Chinese vase urn of the type sometimes known as a “double dragon”.
Allowing for some stylistic variations in calligraphy the reign marks, reading from right to left, appear to be for the Ching Dynasty, Ch’ien Lung (Qianlong Emperor) 1735-1796. Some sources indicate the marks were in use from 1736-1795.
The question is, are the marks authentic? On these kinds of pieces they almost always aren’t. Bronzes like this were highly copied in the very late 1800s to early 1900s for export to the west, complete with a copy of the original mark. They weren’t intended to deceive. Faithfully copying the piece together with the reign markings was seen as ‘respectful’ to the artistry of the original.
Copies can still have a reasonable value, but nothing like that of an original. I would get someone experienced to look at it to be sure, but I strongly suspect it’s a copy.
There’s a similar example on eBay at the moment (pictured below), which has no reign marks and so is definitely a later copy (probably closer to mid-1900s). The seller wants $230 for it, which in my opinion is unrealistic for what it is. It’s obviously a more modern replica of inferior workmanship and also doesn’t have the nicely aged patina that yours has.
