Amazing Toned Ikes?

Ah yes, the Peacock Ikes. I've heard the stories of how a small bank in Salt Lake city (I believe) placed these dollars in cardboard holders for a promotion and it was in these holders that they acquired their toning (like the tidy-house Morgans). I don't believe that for a second, nor do I believe the coins are naturally toned. I'm almost certain I know who the Doc was, as well. Although some of these coins even made it into pcgs plastic, I doubt very much anymore will.
