The killing of Abbas b. Abu Ja’far by the Turkish General Afshin and the change of the Caliph in the context of numismatics: the discovery of new coins

The early Abbasid fels are considered to be more advanced in style and composition than the Umayyad ones. In the period, when the Islamic civilization started to settle down structurally, the financial system was taken from the RomanByzantine, and the state and land systems were taken from the Persians. There are quite a lot of coins, the composition and writing lines of which were shaped according to the wishes of the governorgeneral. This version is not unique to the region. The coins minted by the governors of Khorasan and Armenia were also decorated with different ornaments and signs. According to our findings, the Kozan (Sis) samples of fels, having two examples in literature, were investigated. As a result of our research, it has been determined that this fels, the ownership of which has not been determined until now, belongs to Abbas, the son of Ma’mun (Abu Cafer). The fact that both coins were found in Kozan and neighboring regions reveals that fels was minted in Anatolian lands.
