| Additional information |
John II Komnenos struck tetartera at Thessalonica as part of the administrative decentralization of Byzantine minting — the city functioned as a secondary imperial mint precisely because of its strategic position on the Via Egnatia. The DECPOT (Despot) titulature on this type reflects the co-emperor status granted to his son, likely Alexios, who was elevated as heir apparent in the 1130s but predeceased his father in 1142.
At half the weight of the standard tetarteron, these fractional pieces remain poorly understood in terms of their precise role in local exchange.
