100 Shillings Monkey, nickel plated steel

Uganda's shilling coinage underwent a significant overhaul in the early 2000s as the Bank of Uganda sought to reduce production costs — the shift to nickel-plated steel from earlier compositions was a practical response to rising base metal prices regionally. The 100 shilling denomination had been in circulation since the second shilling series of the 1980s, surviving Uganda's turbulent monetary history including the catastrophic inflation of the Amin and Obote years that had rendered earlier coinage worthless.

The Schön listing as C144.1 suggests at least one variant exists within the type — likely a die or planchet distinction worth noting if encountered alongside examples of differing surface texture.
