True, so do you feel that it is just a coincidence that this card doesn't have the same strange patterns as the others that were affected by chemicals/glue?

Also, at first glance it does look like the 'incorrect' card has splotches of yellow that are not on the other one, but that could also just be the absence of blue - I can't tell if the correct card has darker green (more blue) in the areas that are yellow on the incorrect card, but looks like it might.

edited: Just so no one thinks I'm arguing, I agree that these are not scrap - just trying to better understand the effects that are causing the color fading, be it sunlight, acid in album paper, glue, chemicals or otherwise.
