10 Dollars Catedral de Brasilia

Palau has issued commemorative silver under its own authority since 1992, leveraging a 1994 Compact of Free Association arrangement with the United States that leaves monetary policy largely nominal — the country circulates U.S. dollars in practice. The cathedral series tapped a long-running Vatican-adjacent commemorative market, with Niue, Cook Islands, and Palau all competing aggressively for the same collector base through the early 2010s.

Oscar Niemeyer completed the Catedral Metropolitana de Brasília in 1970, sixteen years after the broader Brasília project was commissioned under Kubitschek's aggressive interior development push.
