20 Lira Mustafa I

Mustafa I ruled twice — briefly in 1617–18, then again in 1622–23 — and both reigns ended in deposition. He was confined to the kafes, the Ottoman palace enclosure used to isolate potential heirs, for nearly fourteen years before his first accession, a psychological toll that contemporaries and later historians have used to explain his erratic conduct in office. The Darphane has issued a number of silver collector pieces in recent years revisiting overlooked or troubled Ottoman reigns, and Mustafa fits that pattern exactly.
