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.
