Playmobil
My my, how I miss my Playmobil guys. There were so many different kinds you could get of the rigid characters. The German toy is quite valuable today and some sets in good condition could be worth more than $800.
Barbie
Barbie first showed her face (and ridiculous body proportions) to the world in 1959. She transformed the way girls chose dolls for themselves and even made her status one worthy of collection with dolls going for as much as $23,000!
