Dinero '1st Granada war' - Alfonso X Greek cross

Alfonso X struck this dinero to fund what Castilian chronicles call the "Guerra de Granada" — the Mudéjar revolt of 1264–1266, when the Muslim populations of Murcia and Andalusia rose simultaneously, almost certainly coordinated with Muhammad I of Granada. The revolt reversed much of what Alfonso had consolidated after Fernando III's conquests, and the financial strain forced rapid, high-volume billon production from multiple mints. Pieces from this issue routinely show die misalignment and uneven flan preparation — not incidental, but a direct consequence of wartime minting pressure.
