I would like to inquire about the silver content of the Aga Khan Silver Jubilee 1982 Medallion.
Specifically, can someone help me confirm the percentage of silver used in its composition? I have tried researching the internet and also looking for a hall mark but no avail.
I am interested in understanding its material value and authenticity so any details regarding its purity, weight and minting specifications would be greatly appreciated.
Thank you for your assistance.
