Stamps

Back in the pre-internet days, people actually wrote letters to friends and loved ones. Along with these letters came stamps. Now, these items are as rare as the letters themselves. A 1997 sheet of a rare stamp could sell for thousands of dollars, but with stamps, the older these are, the higher they cost.

Happy Meal Toys

Happy Meal toys don’t cost much nowadays, but the value of older ones have appreciated, not by much, but by a good margin. The Super Mario 3 collectibles, for instance, have sold for $400 on eBay. If you still have some of these stashed, it may be time to look into their value.
