Steve,

Thanks so much for the information, it kind of gives me a picture in my mind of how the process "sorta" works. Since I have never been in the printing industry I didn't have much clue. I know I have a few of the, I guess you'd call them, transparencies or negatives as well w/the varying colors. For whatever reason I've always liked the odd-ball stuff.

By the way, how do you tell what color your plate was originally?

Marty,

Thanks for the link; I don't know why I missed that since I'm interested in the plates or any other production process of the production of the cards.

Hopefully, one day, more will be found or come to the market, but as Steve said they were probably reused or sold for the aluminum.
