Philip IV inherited the Duchy of Milan as part of the Spanish Milanese — a possession Madrid treated primarily as a military staging ground for moving troops along the so-called Spanish Road toward the Habsburg Netherlands. Coin production under his name in Milan was consequently irregular, subordinated to fiscal demands of nearly continuous warfare: the Thirty Years' War, the Wars of Castro, the Franco-Spanish conflict that ground on until the Peace of the Pyrenees in 1659.
The long reign span of this type means significant die variation exists across issues. MIR 359/2 distinguishes this subtype within a series where attribution requires close attention to bust and legend details that shifted across decades of intermittent striking.
