Copper Scroll
The Copper Scroll is one of the Dead Sea Scrolls found in Cave 3 near Khirbet Qumran, but differs significantly from the others. Whereas the other scrolls are written on parchment or papyrus, this scroll is written on metal. Unlike the others, it is not a literary work, but a list of locations at which various items of gold and silver are buried or hidden. Wikipedia article.
