RESEARCH REVISION 22 · 12 OCTOBER 2026
New research tests the remaining modern roots against legislation, contracts, government accounts and monetary histories. Same-unit renamings remain profile continuity.
All inherited endpoint codes now have an explicit predecessor review. A missing predecessor means research remains open. No currency has been certified as created de novo. Founding standards and earlier forms of the same currency are identified separately.

Antillean and Caribbean guilder names now share one account-unit profile. Ottoman lira, Liberation kip and Salvadoran peso epochs are retained within continuing identities. Historical URLs resolve through explicit aliases.
The older Cambodian riel is separated from its interrupted 1980 restoration. An Egyptian medin/para account unit is admitted from 1524 evidence but remains disconnected. The Haitian colonial bridge is retained as a research proposal, not admitted as ancestry.
| Claim | Status | Finding | Sources |
|---|---|---|---|
| C1161 | supported | Zurich legislation converted Zurich-gulden money contracts into federal Swiss francs at one gulden to 2⅓ francs. The legislative act dates from 28 January 1851; implementation is scoped to the 1851–1852 federal reform. | S551 |
| C1162 | supported | The 1851 Zurich law converted contracts labelled Reichswährung, including Schaffhausen, Thurgau and St. Gall currency, into federal francs through a separate statutory rate. The legislative act dates from 28 January 1851; implementation is scoped to the 1851–1852 federal reform. | S551 |
| C1163 | supported | Section 3 converted old Swiss-franc contracts at sixteen old francs to ten Zurich gulden, then to federal francs. The legislative act dates from 28 January 1851; implementation is scoped to the 1851–1852 federal reform. | S551 |
| C1164 | supported inference | Hong Kong law converted specified public sterling payments into dollar payments at 4s2d per dollar from 16 February 1864. Assignment to the later distinct Hong Kong dollar is a qualified regional-continuity inference. This is a public-account contribution, not its sole founding ancestry. | S560 |
| C1165 | supported inference | 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. | S560 |
| C1166 | supported | 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. | S561 |
| C1167 | supported inference | The Curaçao/Antillean guilder developed from the Dutch monetary system introduced in 1827 into a separate territorial system documented by the wartime period. The 1827–1945 range is a research envelope; the legal separation date remains unresolved. | S563, S564, S562 |
| C1168 | supported inference | Cabo Verde’s real/escudo continuity is provisionally traced to regional differentiation from Portuguese-real accounting during 1853–1865. Local currency arrangements and issues support this qualified branch; the exact account-law boundary remains open. | S565 |
| C1169 | supported inference | 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. | S566, S567 |
| C1170 | qualified | Liberia’s 1935 dollar definition matched the US dollar gold content; later law provided parity and interchangeability. This is an optional founding-standard reference, not demonstrated account-unit succession. | S345 |
| C1171 | supported inference | North Korea’s December 1947 reform separated its currency from the common Korean account system by replacing Bank of Chosen and Soviet occupation notes with a sole northern settlement currency. The law directly supports conversion; identifying a distinct northern currency is the territorial-branching inference. Soviet notes are instruments in the common accounting unit, not a ruble parent. | S570, S571 |
| C1172 | supported | In June 1976 the Vientiane kip was withdrawn in favour of the separately circulating Liberation kip, at 20:1; the Liberation kip belongs to the modern Lao kip continuity despite its 1979 rescaling. No precise 1976 day asserted. | S572, S573 |
| C1173 | supported | The royal Lao kip replaced the shared Indochinese piastre as legal tender for payments in May 1955. National separation, not mere local banknote design; exact conversion rate not needed or asserted. | S573 |
| C1174 | supported | The Cambodian riel replaced the shared Indochinese piastre in 1955, ending the common monetary arrangement. Applies to pre-abolition riel; not a direct uninterrupted edge to 1980 currency. | S574 |
| C1175 | qualified | The riel was reintroduced 20 March 1980 after its 1975 abolition, including use for civil-servant salaries. This is a restoration of the named account-unit tradition, not established redemption of old balances or uninterrupted monetary use. The restoration is retained as an optional relationship. | S574 |
| C1176 | supported | The Maldivian rupee, later called rufiyaa, replaced the Ceylonese rupee in 1947. No exact conversion rate or exclusive currency use asserted; local coin and larin history remains open. | S579 |
| C1177 | supported inference | The federal dollar formalized a Spanish-dollar unit already used for public debt, requisitions and value reckoning, rather than borrowing only a coin weight. The regional account-unit association is qualified; provincial pound conversions remain unresolved. | S582, S70 |
| C1178 | supported inference | Colombian peso/real reckoning continued the inherited Spanish-American monetary system, with the 1821 Congress ordering return to its eight-real silver peso. This is a qualified regional branch; local wartime stages and incomplete implementation remain open. | S584 |
| C1179 | supported | Panama’s own monetary system succeeded Colombian currency in circulation at independence; the balboa was established in 1904. | S473 |
| C1180 | supported | Cuba’s national peso replaced local Spanish-gold peso accounting through the 1914–1916 monetary reform. | S585, S586 |
| C1181 | supported inference | 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. | S67 |
| C1182 | supported inference | Salvadoran peso/colón accounting developed from the Spanish-colonial peso of eight reales retained during the Central American Federation. This is a qualified regional branch with unresolved local stages, not an exact founding date. | S589 |
| C1183 | supported | Zurich government sources of 1803 reckon in local gulden. | S552 |
| C1184 | supported inference | Zurich 1803 records also reckon in old/Helvetic francs. | S552 |
| C1185 | supported inference | The 1831–1832 Organic Regulations recognized leu accounting. The 1867 reform decimalized and rescaled it: one new leu equalled two old lei and 28 parale. | S553, S554 |
| C1186 | supported inference | Ottoman and republican lira are grouped as one continuing account unit. The 1925 law replaced Ottoman paper with paper of the same amount and legal character. CBRT dates the Republic first issue to 5 December 1927. In 1844 silver kuruş and gold lira were convertible at 100:1. The 1927 note replacement is an instrument transition; this continuity assessment remains qualified. | S555, S556, S557 |
| C1187 | supported inference | By the mid-eighteenth century, Ottoman prices and state obligations were expressed in kuruş. Its association with the continuing lira profile is qualified through the retained kuruş–lira accounting structure; circa 1750 is an observation, not a birth date. | S557 |
| C1188 | supported | Egypt’s medin, called para in the 1524 code, remained its leading account unit into the eighteenth century. | S557 |
| C1189 | supported | The 14 November 1885 decree defines Egypt’s pound as 100 piastres and temporarily retains earlier silver at official tariff. | S558 |
| C1190 | supported inference | The 2025 Caribbean-guilder legislation carries Antillean-guilder deposits and legal instruments forward at 1:1. The two names are grouped as a continuing account unit under the project identity rule; this classification is an explicit inference. | S562 |
| C1191 | supported inference | Cabo Verde had locally differentiated real issues by 1865 and escudo accounting from 1914. This is a qualified extension of the existing identity; the 1977 issuer change does not create another currency. | S565 |
| C1192 | qualified | An 1895 inquiry into Macao lottery finances recorded pataca-denominated arrears to the provincial treasury. Association with the continuing pataca identity remains qualified. | S568 |
| C1193 | qualified | Liberia’s 7 June 1935 statute established a national dollar account unit, reenacted in the 1956 Code. This is an earlier observation, not evidence that coin issuance in 1962 created the unit. | S345 |
| C1194 | supported inference | The Liberation kip circulated in a separate Lao zone before national adoption; its 1979 exchange 100 old to 1 new is retained as a rescaling within the modern Lao kip profile. 1968 founding date is research-history report; 1976 existence corroborated by the contemporary World Bank report. Kangkai predecessor boundary not adjudicated. | S573, S572 |
| C1195 | supported inference | Nepal’s rupee was already an account unit in an 1807 royal endowment. The nineteenth-century mohar rupee was reckoned as two silver mohars; 1945 paper currency exchanged at par with mohar-rupee coins. Earlier 1807 and 1945 observations firm; long-span continuity qualified. Do not add a 1932 mohar→rupee edge based on coin catalogue labels. Distinct paisa-rupee and Gorakhpuri-rupee accounts remain candidate branches. | S575, S576, S577 |
| C1196 | supported | 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. | S578 |
| C1197 | supported inference | A July 1765 agreement allocates the Bengal Nawab’s annual government allowance in sicca rupees. Association with the later Calcutta sicca profile is a qualified regional continuity; intervening standards and local ratings are not fully adjudicated. | S580 |
| C1198 | supported inference | The Hooghly collector’s March 1773 remittance records revenue collections in sicca rupees. This is a direct accounting observation; grouping it with the later Calcutta sicca remains qualified. | S581 |
| C1199 | supported inference | Jefferson recorded the dollar’s established use in US public debts and requisitions before the federal mint statute. | S582 |
| C1200 | supported inference | The 1821 monetary legislation retained the Spanish eight-real peso system in independent Colombia. | S584 |
| C1201 | supported | The national peso was established by the 1914 law, and practical conversion of accounts to the new system was reported complete by June 1916. | S585, S586 |
| C1202 | supported | Independent Mexico issued compulsory peso-denominated paper in December 1822 while continuing real-denominated coinage. | S67 |
| C1203 | supported | The Salvadoran peso was renamed colón in 1892 for official documents; monetary reform and naming do not create a separate currency identity. | S587, S589 |
| C1204 | supported | The 1862 law established the national peso from 1 January 1863 and altered its account subdivision; it does not by itself prove a distinct predecessor under the no-rescaling rule. | S588 |
