Joel's coinage exists in two distinct types, most clearly seen in the silver and bronze coinage, where the flans changed from compact, thick flans (which may have helped against deterioration) to broader, thin flans, and the busts from facing busts to busts in profile, an order suggested by overstrikes on bronze coins. This particular type saw the temporary revival of the 'TOYTO APЄCH TH XⲰPA' legend, although heavily abbreviated and with the addition of 'XY', which might stand for 'ΧΡΙCTOY', thus changing the legend to something akin to 'May the Sign of Christ please the country'.

The king's name is biblical, referring to the prophet Joel, whose eponymous book describes how locust plagues and droughts afflicted Israel, but that repentance in the face of God would bring deliverance. Considering the declining fortunes of Axum at this time, this name would have been particularly poignant.
