Without any "coat of arms" or other graphics, all I really had to go on was the 1308 date (corresponding to 1890/1), and I wasn't seeing a match amongst any of the Arab kingdoms I could think of. Finally I was able to determine that it was a 5 centimes of Sultan Said Ali bin Said Omar, who "ruled" the island of Ngazidja as a French Protectorate.
Despite the date, it turns out this specimen came from a 1901 restrike. It still proclaims Said Ali as Sultan when in fact he'd been banished to Reunion Island 9 years earlier.
