The design of the medallion is based on the Austria-Hungary Empire 4 Ducats gold coin struck from 1872 to 1915.
The medallions were supposedly minted in Alexandria Egypt by local jewelers in the early 20th century for sale to tourists.
Some have appeared as part of ornate necklaces or "belly dancer" costume coins.

The Vienna Mint makes restrikes these coins with the 1915 date for sale as bullion coins.
One of these coins was used as a prop coin in the 1957 Michael Powell and Emeric Pressburger film "Ill Met by Moonlight". There is an article on my website about the film under "Coins in Movies". The link to my non-commercial website is in the signature line.
