Might be old enough to look aged while still not being antique. Could be an antique. Could be a sword-like object meant to be nothing more than a decoration. It just isn’t possible to tell over photos. Someone knowledgeable on Chinese sword history would need to look at it and possibly need to disassemble it. I can’t help you with the writing on the blade, but lots of modern pieces have writing as well so that isn’t an automatic clue.
