The "La Madrileña" issue belongs to Real Casa de la Moneda's ongoing local and regional collector series — pieces denominated in euros but with no legal tender status under the European Central Bank framework, circulating instead as privately-issued numismatic tokens sold directly by the mint. Spain's mint has produced dozens of these since the mid-2000s, targeting the domestic souvenir and beginning collector market rather than numismatists proper.
KM#1500 is a round catalog number, suggesting a registry milestone entry rather than an organically assigned reference.
