1/2 New Dollar

Taiwan's half-dollar denomination was effectively obsolete before this series even ended. Inflation throughout the 1980s and 1990s steadily eroded its purchasing power to near zero, and the coin persisted largely through institutional inertia rather than any practical demand. The Central Bank finally discontinued the type in 2004, by which point examples had largely vanished from circulation — not through wear, but through abandonment in drawers and jars across the island.
