Some have St.Charles Borrome's image on the back and others have Pray for Us on the back... 

We have two different styles of these medals that we get from our importer (shown in pictures below). Based on what inventory is available for quickest shipment, you may receive either one of these medal styles. They are both of the same subject but have a slightly different style to the design.
