Lot of Religious (Catholic ?) Medals

/ Pendants Lot of 5 religious medals. I am not an expert in religion buy believe these are all Catholic prayer / protection medals / pendants. I am not sure what the metal content is. I am super weird about how I handle any religious item and do not test them. Note: it appears as if the heart shaped pendant was repaired many years ago as there is brown glue / adhesive present. Also, the glass encased pendant shows some tarnish on the inside. Note: Most of my jewelry is pre-loved. I only wipe down jewelry. I do not deep clean any jewelry before shipping. I am not a professional and do not want to risk damaging any vintage item. There may be a small amount of verdigris. I will note any flaws/defects. Lighting might affect the colors in the photos. I will try to describe as accurately as possible. Please see all photos and do not hesitate to ask questions.
