50 New Dollars

Taiwan's 50 New Dollar coin has circulated continuously through one of the most politically ambiguous monetary situations in modern numismatics — issued by the Central Bank of the Republic of China, a government that officially claims sovereignty over the mainland while being recognized by fewer than fifteen nations. The denomination itself was introduced as part of the 1981 coinage reform that replaced the old yuan series, though this specific type dates to a 2001 redesign.

The copper-aluminium-nickel alloy was chosen partly for its resistance to the subtropical humidity that accelerates corrosion in Taiwan's climate.
