Alfonso X's final years were consumed by the second Granada conflict and, more ruinously, by the rebellion of his own son Sancho. The crown's finances were under severe strain, and the billon content of late issues from Toledo reflects deliberate debasement rather than supply problems — Alfonso had already exhausted considerable silver reserves funding his ultimately futile claim to the Holy Roman Empire throne. AB#271 is attributed to this compressed window between 1277 and 1284, ending only with Alfonso's death at Seville, effectively abandoned by his kingdom.
