10 Euros Peter Paul Rubens

This coin belongs to Spain's long-running commemorative series honoring figures from the history of Western art — a program that has produced dozens of issues since the 1990s and whose collector appeal rests almost entirely on the subject chosen rather than the striking. Rubens is an unusual inclusion: he was Flemish, not Spanish, but spent formative years in Madrid as a diplomatic envoy for the Spanish Crown, using his access to the royal collection to study Titian extensively. Philip IV trusted him enough to send him on a secret diplomatic mission to London in 1628.
