Just to put a nail in this coffin, it is not exposure to sunlight that turns the 1999 EX base cards into a even shade of gold. Here is a scan of the base card, which I put in the windowsill at the beginning of June (I wrote the date on it in blue sharpie) and the same card today. I wrote the date on it again with the same sharpie. The marker faded badly enough that it's pretty much gone, but the plastic card "stock" remains crystal clear.
