Okay, I didn't find them outright, I must have obtained them somewhere (I can't remember where/when) but I was looking through the safe for something else and stumbled across the roll, all uncirculated, the roll stamped 1968 S Seattle-First National Bank. I decided to take a close look at them all. Yes, they're all 1968 S, appear never to have been in circulation, and none are doubled dies. A few have evidence of machine doubling, a few have the "W" in 'WE" mashed against the upper rim, and many have weak mint marks. I had a good time.
