Got any LEGO sets you never got around to opening? Those may be worth big money now!

Researchers at Moscow’s Higher School of Economics actually found that retired LEGO sets actually appreciate in value faster than gold or jewelry.

Collectors are willing to pay an average of 11% more every year for one of those sets! So pick yourself up some LEGO Star Wars ships while they’re on sale and place them somewhere in your home where your kids won’t find them. Instant money!!
