The picture shows all (12) Different Religious Medals / Charms in this lot. I believe that these are all Catholic or Christian medals. They are all made of metal and two are in their original backing. I do not know when these were made. One of these slides open and one is in the shape of a key.
All of these for one price! To judge the sizes the left card measures 1-7/8" x 2-1/2". They appear to range from good with wear to near mint condition.
