Here is a group of 15 bronze pendants/medals that have images of people swimming, looks like gymnastics and a person with a rifle, maybe skeet shooting?  The are 7/8" x 1 3/8".  We really do not know what they were used for, maybe sometime of meets, not sure but hopefully someone will know and pass along much appreciated information to us.  Some are darker then the others along with some corrosion with one having more corrosion.
