5 Euros Pamplona

Issued as part of Spain's long-running "Capitales de Provincia" series, this piece commemorates Pamplona — capital of Navarre and a city whose municipal identity has been a recurring point of friction between the Spanish central government and Navarrese regionalists. The series ran through the 2000s and into 2010, producing low-mintage collector pieces for each provincial capital with limited secondary-market depth.

Navarre's unusual fiscal arrangement — the Convenio Económico, which grants it tax-collection autonomy denied to most Spanish regions — gives Pamplona a political weight outsized for a city of its population.
