Liquid Pistol
Besides coins and guitars, perhaps, guns are next on the most collected and valuable list. In particular, this liquid pistol sold for $2,500! In reality, it’s value could be much higher than a collector. The pistol was invented by Paul Giffard back in 1872 and afterward, bought by a manufacturing company for one million dollars. It was so revolutionary since it did not need any gunpowder to shoot, and only around 100 still exist currently.

Wayne’s World Car
Of course, we’re all familiar with the hilarious SNL skit turned movie, Wayne’s World. Despite being filmed in only 34 days, the movie made close to $200 million! In the film, perhaps you recall the 1976 AMC Pacer called the “Mirth Mobile.” Rick heard the famous vehicle was for sale in Florida, so he planned a trip. Though Rick paid $9,500, with some work it could reach a value of $15,000.
