I looked at a black Rogue today and one of the clips was peeling just like what you are describing. The color underneath was a shiny rusty color.I just received the purple tea rose dinky 24 from coach. It came factory wrapped but the chain strap looks like it has rust on it. I can scrape off the residue with my fingernail. How is this even possible with a brand new bag? The hardware is black copper. I can't exchange it either because it's now sold out.
