Vintage Charcoal Gray Beaded Rosary with a Rich Patina

Vintage silver rosary. It has charcoal gray plastic beads. The silver metal has a rich and grungy patina from age. The Crucifix has a hole drilled into it which makes me wonder if it was once a stanhope. Opening is 23" and the front piece is 5 3/4" long. Center metal and crucifix have very fine details. Weight: 14.9 grams.
