I have found people collect things they relate to. Once the folks are gone that remember the old gas stations, Thats when the value will decline drastically.
Look at Glassware and China, 10 years ago it was selling at our auctions piece by piece, Today, those collectors are dead and gone. We sell glassware and china by the box now.
Lets look at the antique and classic cars. Today a 1929 Model A at auction brings, $35,000. Then a 1969 Plymouth Road Runner at auction brings $135,000. The guy that remembered the Model A is dead. The guy that remembers the Road Runner is in the prime of his life, and by golly he is gonna have one.
Just my obersvations
