You hear it on the news every few years: a couple unknowingly sells a valuable piece of jewelry or artwork for pennies during a yard sale. Don't be one of those people.

In the video above by Buzzfeed, we discover seven old household items that are worth a lot more than you think. From vintage Hot Wheels toys that are worth the same amount as a Porsche to old books that can bring in a cool $40,000, you'll want to take a quick peek around the house to see if you have these items lying around.

Of course, just because something is old doesn't mean it's going to be worth a lot of money. Items that are in-demand are more valuable, but once the market becomes over-saturated, the value goes down. The best way to find out the true value of an item is to contact an appraiser, who will not only tell you the value of your item, they should also help you find the best way to sell the item.
