25 Rial - Abdulaziz and Muhammad III Pattern

This copper pattern was struck in 1865 during a particularly fraught moment in Tunisian fiscal history. The Bey of Tunis had signed the Fundamental Pact in 1857 and a constitution in 1861, but the subsequent tax increases needed to service ballooning foreign debt triggered the Ali Ben Ghedhahem revolt of 1864 — one of the most serious uprisings the Husainid dynasty faced. Currency reform proposals circulated alongside the financial chaos, and this piece almost certainly belongs to that context of experimental denominations that never reached production.

The dual-name reference to Abdulaziz — the Ottoman sultan — alongside Muhammad III al-Sadiq reflects Tunisia's nominal vassalage to the Porte, a political relationship that was more ceremonial than practical by this date.
