Banxico says the 1823 Republic retained reales and escudos while changing coin designs.

Banxico describes decimal coinage in 1869–1905, with interruptions, and a gold-standard reform in 1905.

Mexico introduced one new peso for 1,000 old pesos on 1 January 1993; dropping “new” in 1996 did not repeat the conversion.

NLB describes Spanish/Mexican dollar use and the 1874 acceptance of Japanese yen and U.S. trade dollars in the Straits.

Shanghai Museum documents Spanish and Mexican silver-dollar use in coastal China and later domestic silver-dollar reforms.

Mexican dollars were another input to Hong Kong’s local silver-dollar standard.

The Straits dollar displaced Mexican dollars among several circulating silver-dollar currencies. Other trade-dollar inputs remain to be individually traced; 1899 note issue predates the new coin.

Hong Kong’s locally issued dollar system developed within accounting legally denominated by reference to the Mexican dollar; the 1864 law makes local cents and mils fractions of that dollar and converts public sterling obligations into it. Qualified local differentiation; compresses development into a territorial unit. No exact date of separate currency identity is inferred from the first local coin issue. Supersedes standard-only treatment of the existing MXN reference, rather than adding duplicate edge.

Act 1045 made obligations in Mexican local currency enforceable as Philippine-peso judgments, allowed settlement in Philippine pesos, and extinguished the old obligation upon payment. Partial input to a multiple-currency replacement. The conversion was adjudicated by value, not a universal 1:1 exchange. Do not infer merely from purchase of Mexican silver as bullion.

Macao adopted the local practice of accounting for a Mexican silver dollar as one pataca into its territorial currency. The 1894–1906 association is qualified; neither the first note issue nor the later Hong Kong-dollar peg establishes a currency birth.

Corrected interpretation: Revision 27 supplies a new evidence basis for R-V23-009. This is explicit adoption of an existing monetary account, not etymology or coin weight alone. Local issue chronology remains bounded; the ancestry is supported. Replacement evidence: C1611.

Independent Mexico retained Spanish peso/real reckoning while developing its own monetary system. A qualified territorial continuity based on the retained accounting system; contemporary fiscal law is still sought.

Independent Mexico issued compulsory peso-denominated paper in December 1822 while continuing real-denominated coinage.

The locally used Mexican-dollar reckoning differentiated into the Straits dollar through the1903–1906 reform: Mexican dollars were the1890 standard within existing commercial dollar accounts; local dollars replaced them and obtained an independent exchange value.

Macao pataca accounting was explicitly established as one Mexican dollar per pataca in 1894; the subsequent local currency adopted that accounting unit.

The Indochinese piastre developed from local Mexican-dollar/piastre reckoning after unsuccessful franc introductions. Conant describes acceptance of the piastre unit and local fractional issues followed by1885piastre coinage; the colonial common currency retained Mexican-dollar parity. This is regional account-unit adoption, not descent inferred only from a metal standard.
