Story highlights Laurie Rimon discovered the 2,000-year-old coin while hiking in eastern Galilee recently

"This coin is rare on a global level," an Israel Antiquities Authority coin expert says

The coin would have been too valuable for everyday use, so its presence is a mystery

Jerusalem (CNN) The shiny object was just sitting there in the grass, waiting to be found. It was a 2,000-year-old gold coin with the face of a Roman emperor, so rare that only one other such coin is known to exist.

Laurie Rimon discovered the gold coin while hiking in eastern Galilee recently, not far from the biblical site where it's written that Jesus walked on water and performed the miracle of the multiplication of the fish and bread. Rimon, from a kibbutz in northern Israel, turned it over to the Israel Antiquities Authority . It was her own little miracle.

"It was not easy parting with the coin," she said. "After all, it is not every day one discovers such an amazing object, but I hope I will see it displayed in a museum in the near future."
