Polly Pocket ($1,275)
Want some more cash in your pocket? The solution might be found in your childhood collection of Polly Pocket toys. If you happen to have complete sets with all their tiny pieces, you could likely sell them for hundreds of dollars to collectors.
These were a big hit among children when they first came out in 1989. They were so portable that it was easy to carry along to friend’s houses and even sneak to school! It should come as no surprise that a full set is hard to find nowadays.
