Nokta FoRs Gold, a Gold Cube, 2 Keene Sluices and Lord only knows how many pans....not to mention a load of other gear my wife still doesn't know about!
Good find. It's definitely Catholic. The bottom limb of the cross includes the design for what is known as the "Miraculous Medal". That design was approved by the Catholic Church in 1836 following the apparitions experienced in 1830 by the French nun Catherine Labour? in Paris. There's a Wiki page here:
The design has been in use (across Europe in particular) ever since. Some of the medals or items including the medal design have a date of 1830, but that's the date for the apparitions, not the item. They all date to 1836 or later.
Nice find indeed. The iconography isn't Orthodox, Greek or otherwise, although the shape might lead one to think in that direction. I believe Red-Coat has it correct.
For those reluctant to click on the link I provided:
I believe the original Catholic medal design was copyright protected, so reproductions of it often have stylistic differences... but the core elements and their symbolism are the same.
