16. The Copper Scroll
Between 1946-1956 the Dead Sea Scrolls, a collection of 981 texts in the caves of Qumran. The copper scroll, in particular, is said to describe copious amounts of gold and silver–yet no one knows where it may be. There is some confusion about the date of the scroll, but multiple archaeologists agree on around 70 CE. It’s pretty fascinating that there might be a lost treasure hidden in the world.
