Remember these bad boys? Summer was incomplete without them. All of our memories involve running around the neighborhood launching assaults on rival kids. Surely it wasn't just us? Despite water guns being a fairly run of the mill item, the Super Soaker managed to achieve cult '90s status, making it worth quite a bit of money these days. Not only did you get the good memories, you'll also get your cash back!
A vintage Super Soaker Monster XL is the holy grail of Super Soakers and one of the largest water guns ever sold, so if you own one of these you can really cash in. They're worth about $500 today. The Super Soaker CPS, which was known for its powerful shot, is worth around $300. Now we wish we kept all of our old water weaponry!
