50 New Dollars

Taiwan's shift to bimetallic coinage in the mid-1990s coincided with a period of acute cross-strait tension — the People's Liberation Army conducted missile tests in the Taiwan Strait in 1995 and 1996, prompting the United States to deploy two carrier battle groups to the region. The Central Bank pressed ahead with the new denomination regardless, and the 50 New Dollar entered circulation during one of the island's most politically charged moments since the 1958 Matsu crisis.

The Y#556 attribution covers the full 1996–2001 run without distinguishing annual mintage variations, which differed considerably year to year based on demand from Taiwan's robust vending and transit infrastructure.
