10 Dollars St. Peter's Basilica

Palau has issued commemorative religious architecture coins since the late 1990s, leaning heavily on the Vatican series to attract Catholic collectors in Europe and the Philippines. This 2013 piece belongs to that sustained program rather than any particular anniversary or ecclesiastical event — it was a catalog product, not a response to circumstance. Benedict XVI had abdicated in February of that year, the first papal resignation in nearly 600 years, which gave the Vatican unusual global visibility at the time of issue.
