Barbie Dolls
The year was 1959 and a new kind of beautiful doll that looked more like a real woman than the doughy dolls that girls were used to appear in shops. Her name was Barbie, and she rocked the world! The Barbie dolls that the older members of your family held onto will easily go for a huge amount of money, perhaps even $25,000! That being said, the Barbie has to have been left within its box and must be in pristine quality. As for the other rubber ladies in the Barbie universe, you can hope for $10 or $20 at best apiece.
Vintage Playboy Magazines
Yes, there are people out there who amassed Playboy magazines as an investment, rather than for their naughty kicks. While Hugh Heffner might not be with us any longer, his legacy, which commenced in 1953, lives on. But which of his many, many magazines will turn out to be a rewarding stock? You can bet on the prints that came out before 1970, but anything beyond that period will not fetch much money. Playboy magazine was printed in such massive quantities that you will not struggle to find copies of the more famous editions.
