The mysterious T205 cards with GREEN borders....show or tell us of your green T205's

[nat]

I'm resurrecting this old thread because it's what I ran into when looking for information about T205s with green borders. I just picked up this Bender. He was, unfortunately, hole-punched at one point, but other than that he's not in bad shape. The really curious thing is that he's got a paler green color on most of his borders, and spots of darker green along the bottom and the very edge of the sides. He's also got spots where the ink wore off and the cream/yellow card stock shows through (by the tip of the bat).

It's Piedmont factory 25, FWIW.

Some of the cards in this thread seem to demonstrate that there are lighter and darker green T205s, what's strange about this card is that it's both (mostly light, spots of dark). Any idea what this is about? If the difference between light and dark was exposure to sun or humidity or something you'd expect it to be uniform, not leaving spots of dark coloring.
