Yeah, never forget the mass market cheap stuff, made only for the masses who supposedly have neither taste nor culture. And further ruined by being made in the millions, supposedly killing off any chance of collectibility. An amazing amount of those items turn out to be incredibly collectible.

Just off the top of my head:
The aforementioned Varsity.
First generation Ford Mustangs.
Any Harley Davidson from the Knucklehead on.
Single cam Honda CB750's.
