I found this today in a roll of halves. it was obviously in the roll before even opening as it's 1 or 2 mm. larger in diameter. This is a cast piece of tin or pewter, there's a seam around the edge, and the remains of a mount are at 12 o'clock.
Seriously though, it has Latin text, and appears to be for or of a local saint. I am sure some Catholics can shed some light. Nice find!! Gary in Washington
St Benedictine "May we be strengthened by his presence in the hour of our death" Satan chasing medal. Used by Methodists, Lutherans, Roman Catholics. Nice find. Lucky roll. Any silver???!!!!
