Hi all!
I have a medal with the following characteristics:
1. Total weight 15.07 grams.
2. Central part made of gold, 6.72 grams, 23K, diameter 26 mm.
3. Outer part made of gold, 8.35 grams, 18K, diameter 38 mm.
4. Central part could be separated from outer part.
What could it be and how much could it cost?
