Okay so I had to get one more short hunt in for the day, I went back to the public pool site and found a silver cross pendant and a key.. woot woot! I've been wanting to find one of these too :-)
Careful... many of those Catholic charms are only silver plated. It should have a hallmark if it is sterling. Still a nice find, and I enjoy researching the saints and styles.
" Four Way Medals are a unique style of Catholic Jewelry. Instead of being a representation of a specific saint or medal the four way medal contains multiple saints.
First, the medal is shaped like a cross. Each arm of the cross contains a representation of the Sacred Heart, the Miraculous Medal, St. Christopher and St. Joseph. The back of the cross contains images of Our Lady of Mt. Carmel and the back of the Miraculous Medal. Typically the medal also has the words "I am a Catholic, please call a priest." on the back.
Sometimes a four way medal has an additional symbol at its center such as the Holy Spirit or a chalice for First Communion. These medals are sometimes referred to as five way medals. "
Lovely silver cross! One of the most artistically finer ones I've seen on t-net. Sometimes sterling silver does NOT have any markings -- for example, I dug an old rosary my second year detecting which had no marking but was solid silver. It is what it is! Have Fun! Andi
