1 Rupia

Italy's colonial currency for Somalia was administered through the Banca d'Italia but kept deliberately separate from the domestic lira system — the rupia was pegged to the Indian rupee, reflecting the trade realities of the East African coast rather than any Roman economic logic. This issue, authorized under the colonial administration of Italian Somaliland, replaced an earlier series and was itself short-lived, superseded when the somalo was introduced decades later.

Federici both designed and engraved the plates — an unusual consolidation of roles that was not standard practice for Banca d'Italia work of the period.
