In a spot that I've been through a few times, I dug this up. I think it's a Rosary. Not sure what it's made of (no markings...only Italy on the back). It looks to have a little age on it.
Nice rosary and a neat find. I don't believe it's either gold or silver. The left and right ends of the cross show signs of corrosion. That wouldn't happen with gold or silver.
