I know what you mean about the copper look. I just bought a vintage strap on Ebay and parts of it look like copper. The part that gets the most stress is worn down and that part looks silver. A magnetic doesn't stick to it.Hmmm...working on polishing the hardware on my Watermelon Tote and it's pretty frustrating. The ball chain on the hang tag polished up bright and beautiful. The clasp of the kiss lock polished up pretty well though there is some wear at the spot where the stress of opening/closing occurs. The weirdness is the metal on the handles - it is really hard to capture with my phone camera, but no matter how much I polish, it's dull, dingy and gray looking:

And...the pull ring on the zipper looks copper (I know it isn't, but it sure looks it - bright like a new penny!) I'm perplexed...is it just that the brass is really old and discolored and will take a LOT more elbow grease (ugh)? Or is there plated metal on parts of the bag and no amount of polishing will make it shiny again?
On my oldest bag, the buckles are labeled solid brass.
