Hello,
I believe you have a Grano (20 Grani = 1 Tari) of the Order of Malta. The maltese
cross is the
reverse with the date in the angles of the
cross. The
obverse is five cresents with the ruler's name around the edges. I believe the ruler is Emmanuel Pinto (1741-1773), and the coin would have been minted from 1743 to 1773. The reference is
Standard Catalog of World Coins, Order of Malta C#1.
Hope this helps.
David
