A grandfather who thought he had found a precious silver ring in the ground ran for his life after discovering it was a pin attached to a hand grenade.
John Hill, 67, was with his family scouring farmland with a metal detector when he stumbled across the shiny metal loop.
He pulled what he hoped was an ancient ring from the ground but then discovered the ring was attached to a pin hanging out of a live Second World War grenade.

WOW! i could imagine the reaction as “oh what’s this, a ring, why does it have a tab on it, could it be a grenade, i think its a grenade…..RUN!” that being said, pretty easily beats my most interesting find 🙂
