In Spain, in the territories dependent on the Crown of Castile, are known the seals on the fleece coin (copper and silver) that circulated in the seventeenth century, during the reigns of Philip III and Philip IV. These stamps reflect the economic hardships suffered by a state beset by debt and piracy.
