Stamps ($9.48MM)
Remember all the times you made fun of your dad or grandpa for collecting something as insignificant as stamps? I mean, come on. They’re stamps. Jokes on you! As it turns out, these collections can be worth thousands of dollars, and collectors are especially interested in rare and limited-edition stamps. In fact, an 1856 British Guiana 1c Magenta stamp is valued at $9.48 Million.
You might want to start looking really hard through every nook and cranny if you happen to inherit a house from your dad or grandpa one day. You never know if that tiny stamp hidden in a corner might be worth more than the entire house itself!
