| 裏面の説明 | An armillary sphere occupies the central field, depicted schematically with six parallels of latitude, a central ecliptic band, and two meridian circles rendered as intersecting circumferences. The instrument, a personal device of King Manuel I subsequently adopted as a dynastic emblem of Portugal, is shown without a legend or additional ornamentation, presented boldly within an otherwise plain field. The design is characteristic of colonial Portuguese coinage issued for Asian territories during the early sixteenth century. |

João III's administration of Malacca operated under constant pressure after the Portuguese seizure of the city in 1511 displaced the existing Malay monetary system. The calin alloy — a Southeast Asian tin-lead mixture — was a practical concession to local materials and trade expectations rather than Portuguese metallurgical preference. Lisbon had little interest in shipping silver to a garrison perpetually threatened by Johor and Aceh.
The dating span reflects administrative continuity across multiple captains-general rather than a single mint run. Individual issues within this range can differ meaningfully in tin content and flan preparation.
