I have the damier koala wallet, and I have a similar problem with mine. I don't think my hardware is plated with anything, but the top clip part that the koala button slides under scratched up the surface of the button! It is supposed to be solid brass, but i'm not even sure what is going on there. The button is completely discolored in one patch approx. 5 mm across and almost green, it is really ugly. The funny thing is, I haven't had a single problem with the buttons on my manhattan, which uses the same hardware.
I am really disappointed with the quality of LV lately, it seems like this stuff is happening all too often as I check up on the forum with everyone else's experiences.
My best advice would be to stay away from anything with lots of hardware... but sometimes I guess you get stuck with the bad one out of the batch. A long time ago, the zipper on my medium looping (first LV bag) broke and the hardware of the zipper pull also completely tarnished and rusted or something. It was gross! The SA said it was my fault and that I must have allowed the hardware to get wet or something, so paying for repairs would be my only option. Even a cheapo bag from Target with stainless steel zippers would hold up better.
