From the
dealer’s write up:
This example features two counterstamps, both attributed to Izz al-Din, governor of al-Jazirah appointed by Sayf al-Din Ghazi I of al-Mawsil (Mosul). Izz al-Din revolted upon Ghazi's death and took al-Jazirah as independent ruler, a period during which he presumably countermarked circulating coins in his name. This example is struck on a Byzantine anonymous follis attributed to the reign of Michael VII, 1071-1078 A.D. These two countermarks were found applied together on 212 coins in the hoard.
The
Mardin Hoard was a large group of copper coins found before 1972 in the
vacinity of Mardin in modern-day southeastern Turkey. The hoard consisted of at
least 13,500 pieces, including around 2,200 Byzantine folles countermarked by
local Islamic rulers, as reported by N. M. Lowick, author of 'The Mardin
Hoard,' a 1977 book published to document the countermarks found on the coins.
The hoard was important in further understanding patterns of circulation and
countermarking of Byzantine coins still being used in lands recently claimed by
Islamic rulers. Most examples are heavily worn from circulation and many are
countermarked several times, some on top of each other.
