When my wife's mom died, she found a bunch of old one day passes for DL from the 80's. When we used them last year, they would tear off the stub, and give us a ticket with a barcode (would be a Mag strip at WDW, yes?) to use for FP and readmission. They were NOT good for admission to DCA. We were able to keep the original, although they stamped the date on it.
However, look carefully at what they give you. The last day of our visit, the gate CM was on his first day back after surgery, and ended up giving us passes good for entry into both parks, so you may get lucky. It was an added thrill to use tickets with a price of $17.95. I used the last day of a 3 day WDW ticket from 1983 ten years later when the one day price had increased to what I'd paid for 3; also one of my favorite memories (esp. since I had paid for that one.)
Presumeably, unless they were hoppers, you would only be able to do one day/one park.
Cheers.
