1/2 Tanka - Muhammad bin Tughluq

Muhammad bin Tughluq's early billon fractional issues fall within the period before his notorious monetary experiment — the token currency debacle of the 1320s–30s, in which he attempted to replace gold and silver coinage with brass and copper tokens. That scheme collapsed when the sultan proved unable to prevent mass counterfeiting, and the resulting currency chaos forced its abandonment. These small billon pieces predate that crisis and represent the last phase of relatively conventional Sultanate fractional coinage before the experiment destabilized Delhi's monetary system for years.
