1 Peso Galileo Galilei

Cuba's commemorative peso program of the 2000s was prolific to the point of cynicism — dozens of issues struck in small quantities for the collector export market, generating hard currency with minimal domestic circulation. This Galileo piece fits squarely in that pattern. The 2009 date places it well after the series had become a reliable revenue mechanism rather than a genuine commemorative effort.

Galileo's 1610 publication of Sidereus Nuncius — reporting his telescopic observations of Jupiter's moons — was the specific scientific event designated by the UN as the basis for 2009's International Year of Astronomy, which drove a wave of Galileo-themed issues from multiple mints worldwide that year.
