Tanzania switched from the original copper-nickel alloy to nickel-plated steel for this denomination in 1990, a cost-driven decision reflective of the fiscal pressures the country faced following years of socialist economic policy under Julius Nyerere's ujamaa program, which had left the national economy severely strained by the late 1980s. The plated steel transition was common across multiple African nations in this period as raw material costs made traditional alloy compositions increasingly unsustainable.
The plating on circulated examples frequently shows edge wear and base metal exposure — not a strike issue but a known characteristic of the type in used condition.
