Abu Bakr Shah's reign lasted barely a year before Nasir ud-Din Muhammad Shah IV deposed him in 1390, making issues from this period scarce by simple arithmetic of time. He came to power through the support of a faction of Afghan nobles who had grown hostile to the Tughluq central administration, and his coinage reflects a moment of contested legitimacy rather than settled rule.
Billon issues of this type are frequently found heavily corroded — the debased silver content accelerates oxidation in burial conditions, and most examples that survive to modern collections passed through the ground.
