Per your PM request for input on this thread , treasures1984 , I'll chime in with the other members who have the opinion that your item is not one that is antique (100yrs or more) .
If you do plan on selling it as what it appears to have been designed for/after - a charcoal burner - I'd suggest that you tell the buyer that it is not safe for indoor use .
These pesky fellas , or ones like them , are the cause of many problems to the owners , up to & including death via carbon-monox , in countries around the world !
I'm unsure if your item is constructed of primarily brass , or of bronze .
I've got little-to-no clue as to pricing on this item , since it's modern (IMO) , t1984 .... as a little suggested 'tip' for the future ... beware the authentic/ancient appearing 'Chinese' items that have dragons with 5 toes .... back in the old , old days in China , one would loose ones' head if caught with a 5-toed depiction of a dragon (5-toe dragons were for the big-shot emperor ONLY , mostly) .
The best I can guess is that it is of Asian-Pacific manufacture , for the 'designer/export' market .
