1/4 Anna - Faisal without border

Faisal bin Turki ruled Muscat and Oman under persistent pressure from both British commercial interests and rival claimants within the Al Bu Said dynasty. This copper issue was struck at the Calcutta Mint, reflecting the sultanate's deep economic entanglement with British India — the Anna denomination itself borrowed directly from the Indian monetary system, a practical concession to the region's dominant trade currency. The "without border" distinction separating KM#8.1 into Cordry SC#11 and SC#12 points to a mid-run die change, the kind of variation that only became catalogued systematically decades later.
