Looks to be a charm (like the piece in your other thread), this is also copying a Value 1,000 coin of Xianfeng (1851-1861) but from the Board of Works mint. Again, the style of characters is "off", and the incised patterns, indicate this is not an official coin but rather a charm, probably made later.
So I did a little browsing: unless another family produced the same charm, it appears to be an exact match, suggesting a produced coinage...
