71/2 Euros The passage of the strait, Proof issue

The €7.50 denomination sits outside the eurozone's standard circulation framework entirely — Portugal uses it exclusively for commemorative and collector issues, a practice that lets INCM operate outside the European Central Bank's oversight of circulating currency. "The Passage of the Strait" refers to the crossing of the Strait of Gibraltar, a pivotal moment in the early 8th-century Umayyad expansion into Iberia under Tariq ibn Ziyad in 711 AD — an event that reshaped the peninsula for nearly eight centuries.
