I took my metallic brown 227 reissue out dancing and the next day, to my dismay I found the corners had faded to a silverish white color. It might have been there before as I often push back my bag with my elbows instead of lifting it up and I found the corners which had come into contact with the elbows much more damaged than the other corners. I hope this is helpful.
I saw a silver reissue on display at NM and it was horrible looking. You see tiny cracks around the sides, back pocket and around the mademoiselle lock. I bet it someone bought and used the bag and then returned it.
