1/2 Ducaton - Philip IV First type

Philip IV inherited the Spanish Netherlands at seventeen, in 1621, just as the Twelve Years' Truce with the Dutch Republic expired — meaning this coin was struck entirely within the resumed Eighty Years' War. Brabant's mints were under persistent pressure during these years, supplying silver for both commerce and military expenditure across the southern provinces. The ducaton series itself had been introduced in the Spanish Netherlands partly to compete with the Dutch leeuwendaalder circulating heavily in the region.

The "First type" designation distinguishes this issue from the revised ducaton coinage introduced later in Philip's reign, with the transition documented in Delmonte's typology between S#279 and S#280 reflecting minor die modifications rather than a policy change.
