Hey all, found this forum doing some research on these cars after seeing some can be worth quite a bit of money. Found a box with about 30 of them in it. My grandfather owned a Cadillac dealership starting in the 60's and I remember playing with these (maybe not exact ones) at his house. There is also a box with 10 in box ones from 1976 in all different colors. The box that those were shipped in actually has the shipping label from JoHan itself. My questions are, what makes some more valuable then others? Paint color? Year? Model? Would the be worth selling now or hanging on to them? Are there any lists out there that has the complete set of cars/models/colors? The dates range from 1965 to 1979. Thanks for your help!
