The emperor of the Ottomans at that time was His Imperial Majesty, The Sultan Abdülhamid II, Caliph of the Faithful.
He was the last Sultan to exert effective control over the Ottoman Empire. Each Sultan had a 'tughra' (signature) that was unique.
Hamid's tughra is that image in the center of the coin on the left.
The Islamic date, in Arabic numbers, on the other coin is shown as four distinct marks just above the wreath at the base of the coin. Later, in 1923, the Republic of Turkey became the successor state of the Ottoman Empire.
