(CNN) — Hen Zakai loves exploring darkness. In his spare time, he lowers himself into the underground world of hidden caves to navigate the nooks and crevasses of a very different environment.
Zakai was recently spelunking with his father and a friend, all of whom are members of the Israeli Caving Club, when Zakai spotted a shiny silver object in one of the most well-hidden stalactite caves in northern Israel.
As Zakai moved in for a closer look, he found two ancient silver coins stashed inside a nook. The coins were meant to be hidden, perhaps to be retrieved at a later date. Instead, they lay in secret for more than 2,000 years in a small hoard that will give archaeologists a valuable insight into ancient Israel.
