3 Cagliaresi - Filippo III

The cagliarese was the lowest denomination struck for Sardinia under Spanish rule, and Philip III's reign saw chronic underfunding of the Cagliari mint, which operated intermittently and often struggled to source even the modest copper required for these fractional pieces. The island's coinage remained administratively subordinate to Madrid throughout this period, with local authorities petitioning repeatedly — and rarely successfully — for adequate bullion allocations.

The CNI places these among the least documented of the Sardinian copper series, with die varieties poorly catalogued and attribution between Philip II and Philip III pieces frequently contested on worn examples.
