1 Pound Om Kalthoum

Issued to commemorate Umm Kulthum, who had died in February 1975 after a funeral procession through Cairo that drew an estimated four million mourners — one of the largest in recorded history. Egypt's government moved quickly to formalize the tribute in silver, though the coin appeared a full year after her death.

The .720 fineness places it firmly in Egypt's mid-century commemorative tradition rather than the higher purity issues that followed later in the decade.
