Those are gold plated, right? Do you mean that the plating looks uniform all along the contact after using the eraser? That would imply that the discoloration isn't an area where the gold is worn away, but rather a deposit of some sort on top. I wonder if the mating contacts are tinned (or other silver-colored alloy), and that's what gets deposited on top of the gold. Just trying to understand the situation you're describing...
