Son of Mohammad III bin Tughluq. Story goes, his father was returning home from a successfull campaign vs the Sultan of Bengal. At this time the Dehli Sultanate pratically comprised 95 percent of modern day India. Only the Southern tip was controlled by the Hindu Vijayanagar Empire. Firuz, invited his dad to sit back and relax in a toy palace that he had made for Firuz when he was a toddler. Well, the palace was rigged and collapsed, killing Dad. Not a nice son.
Again a very nice specimen ! The name of the caliph is in the lower line on the coin in your upper picture (which is upside down)
Thanks, I was really lucky, Rauch had these two coins in their auction last year. Dehli coins are tough to get in mint state quality. John
