Pewter shiny Coach hobo bag

I purchased this Coach bag some years ago and carried it for a while. It’s a roomy bag. It has an inside zipper pocket and 2 open style pockets. It does have some wear as shown in the pictures. The pewter has rubbed off in some areas revealing a brass tone. I mailed it to Coach and they said there wasn’t anything they could do to fix it. Inside is in perfect condition.
