I know that refinishing furniture, and/or polishing/cleaning certain things can ruin the antique value, so I never clean those types of things, or refinish, etc.
However, I sell al lot of vintage silver, and I want to know what other sellers and buyers think about polishing, for instance, a Mexican SIlver piece. As a better example, I have a silver bell by a well known silversmith. It needs a good cleaning, but I don't collect bells, so I do not know what to do.
I usually do not clean jewelry, unless it is really physically dirty, but I also have a lot of experience cleaning jewelry, so I am comfortable doing it. But, what do buyers think?
Additionally, any antique copper buyers out there? I have a rare, signed, American kettle, but do not know what to do. The auctions I see have the metal shiny, but many of these pieces are from very high-end collectors, and may be coated to resist tarnish.
Brass? (Objects and jewelry)
Clothes- I would assume always clean?
