9. Look In Your Attic

This one might not work for everyone, but for those of you who have boxes and boxes of unused stuff in your attic (basement or garage, too), this could be lucrative!
People across the U.S. and beyond love collecting all manner of knick knacks and you might be sitting on a treasure trove, especially if you yourself have inherited some items from older family members. Take an Action Comics book from December 1938 in mint condition which sold for a staggering $40,000 recently.
Of course, don’t get your hopes up about the extremely rare stuff, like the Honus Wagner baseball card worth at least $3 million, but you might have stuff that’s worth at least a couple of hundred bucks. Pair this up with a little spring cleaning and you’ll have yourself some new storage space and a little more chipped away at your savings.
