I have this since I was very young (I have had it approx. 15 years now), no one including myself is sure where I got it. I can’t really find anything concrete about in online, so I thought I would try something like this.
Weight: 1.6 oz (according to a similar post I found online)
Diameter: 6 cm
Width: 4 mm **I am unsure what metal it is made of, but it is very hard and doesn’t get scratched (feels like a large coin)
It used to have a chain with it, so I assume it was used as some sort of necklace.
You have shown the front but what is on the back ?? If nothing is on the back then it was always intended as a necklace since that part could not have been seen !!
The hole for the chain was not a home done job,, it was factory drilled !! It was not a medallion for anything else,,, just a decorative necklace !!
