Treasures found under the seats

While stripping a Black 67 GTS for paint,I pulled off the rear trim panel between the tail lights.On the panel the bottom lip is rolled up and someone had slipped 1967 pennys into the slot all across the back of the panel.They had to be put there on the production line as we got the car from the original owner and it had never been apart.I also once found a paper Dixie cup in a 71 GTX that had Chrysler Corp. printed on it.It had a picture of Tech on it.Tech was Chryslers animated teacher on training films that they sent to the dealers in the 60's and 70's.I bought a 1970 Superbee that was in storage since 1976 and when I pulled out the back seat,I found the paper backs from the Scat Pack Bees from when they were installed in the windows at the factory,I also found a paper sack with some amp tubes in it and a reciept dated 1970 and made out to Pfanenstiel polka band.There was also a pit pass from Great Bend Dragway.
