The Decayed Hat of Farid Swagboy is a 1028 years old piece made by Farid Swagboy, a crime lord living in Istanbul / Constantinople / Byzantium.
Considering its age and the quality of the work, people consider it of no value.
It is engraved with central asian patterns and some symbols pertaining to Manichaeism.
This piece doesn't exist, but as a legend. It is said that in the year 1096, Hayat Swagboy, the owner, made use of it in Istanbul / Constantinople / Byzantium to empower the Swagboy family. Now it is lost, or broken, we will never know.
