RARE Vintage Silver ROME 4 Way Cross Religious Medal Sacred Heart, St Christopher, St Peter

VINTAGE marked Ricordo Rome four way catholic medal featuring Sacred Heart, St. Christopher, St Peter and a Miraculous Medal. This medal measures 1 & 3/16ths of an inch tall with the bail. The middle of the cross is St Peter's Square. The bottom has two hallmarks that I am not familiar with- one of the hallmarks does say ST, I am not 100% sure if that means this is a sterling medal. It is untested for content- because I do not acid test anymore for environmental reasons. This medal does not react to a magnet and is tarnished and will need cleaning.
