The contemporary survey of Siam’s 1928 law says the silver tical remained unlimited legal tender under the name baht. A naming and standard change is retained as profile continuity, not a separate ancestral currency.
Sources and qualifications →The 1856 Anglo-Siamese agreement reckoned duties and fees in ticals and salungs, documenting the earlier baht/tical account unit. 1826 duty is reported retrospectively; 1856 is direct dated observation. Same-unit extension, not tical→baht replacement.
Sources and qualifications →La Loubère records tribute obligations in ticals and identifies Baat as the Siamese name for the tical. Association with the continuing baht is qualified across the intervening centuries; alternative names and foreign exchange comparisons create no separate parent.
Sources and qualifications →The1536 Vat Khema inscription records a six-tical silk purchase, providing a dated monetary-price anchor earlier than the1687–88 embassy observation. Assigning the local Sukhothai-region tical to the broader Thai baht continuity is qualified; the translation establishes a price unit, while exact regional metrological and legal continuity through later centuries remains incomplete.
Sources and qualifications →The Three Seals Code compiled in1805 contains monetary body-price schedules explicitly stated in baht and tamlueng and used to calculate death compensation. Original baht entries provide a legal account-unit anchor for the continuing Thai baht, earlier than the1856 treaty observation. The age of underlying Ayutthaya clauses remains uncertain.
Sources and qualifications →The Siam commercial agreement ratified17January1827 assessed Bangkok vessel duties at1700 or1500 ticals per Siamese fathom of breadth. This is a dated fiscal obligation in the continuing tical/baht account unit. The1856 agreement references the earlier1700-tical duty.
Sources and qualifications →Aymonier attributes ten-tiền ligature subdivision to Annamese imitation. This establishes limited accounting influence, not ancestry of the whole Cambodian bat account. Thai derivation and piastre absorption remain unverified.
