Hello, Can someone give me more information, I think mint is Sardis.? Rich Found information see posted photo below…
Mine has the “Big Knob Throne” like yours... LIFETIME ALEXANDER Makedon Alexander III Lifetime Tet Myriandrus mint-Alexandria near Issus
Congratulations on acquiring a great coin. When you add the information to the photo, the convention is to list the years of the reign after the name, and the mintage year(s) after the name of the mint. Something like this: Alexander III, 336-323 B.C. AR tetradrachm Sardes mint, 318-315 B.C.
