The State of Yucatan was distinct in the Mexican republic due to its immense concentrated wealth, making it one of the few regions capable of supporting multiple banks of issue simultaneously. The banking landscape was dominated by two primary, competing institutions: El Banco Yucateco and El Banco Mercantil de Yucatán.

El Banco Mercantil de Yucatán was established by a coalition of traditional Yucatecan businessmen and landowners. The financial backbone of this institution was the powerful regional trading house, Eusebio Escalante é Hijo. The founding board of directors was headed by Eulogio Duarte and included prominent regional figures such as Eusebio Escalante Bates, Rafael Otero Dondé, Raimundo Cámara Luján, and Joaquín Peón. Eulogio Duarte secured the official government concession to establish the bank in the state capital of Mérida on September 18, 1889, and the institution opened its doors for business on March 4, 1890.

The bank experienced rapid growth mirroring the broader henequen economy. Its original capitalization was set at $750,000 pesos. As operations expanded, this capital was officially increased to $1,000,000 on April 1, 1893, and further expanded to $1,750,000 on December 15, 1899. Following the implementation of Limantour's 1897 banking reforms, El Banco Mercantil de Yucatán successfully secured a new contract on September 18, 1897, allowing it to continue its highly profitable role as a bank of issue under the new federal guidelines.

The 50 Pesos banknote of the Gobierno Constitucionalista, authorized under the decree of July 21, 1915, emerged as a direct result of Venustiano Carranza's consolidation of power during the Mexican Revolution1. Carranza's return to Mexico City and his establishment of a unified government were made possible by a series of decisive military victories engineered by General Álvaro Obregón. In the spring and summer of 1915, Obregón's Constitutionalist forces decimated Pancho Villa's División del Norte in the Bajío region, triumphing in the massive Battles of Celaya (April 1915), the protracted Battle of León or Trinidad (where Obregón notably lost his right arm), and finally at Aguascalientes in July2. These victories effectively broke Villa's military supremacy, allowing Carranza's Constitutionalist army to march triumphantly into Mexico City in August 1915

Upon securing the capital, Carranza immediately moved to stabilize a shattered economy plagued by hyperinflation and a chaotic mix of regional fiat currencies. He declared all previously issued paper money from rival factions void and decreed the creation of a single, unified national currency—Los Infalsificables4. However, because these high-quality notes were contracted to the American Bank Note Company (ABNC) in New York, they would take time to print and deliver. Prior to their arrival, the government relied on an interim currency printed domestically at the Oficina Impresora (Government Printing Office), which included small-denomination cardboard cartones and Obligaciones Provisionales del Erario Federal (provisional treasury obligations).

To underwrite the creation of the Infalsificables and theoretically guarantee their circulation, Carranza decreed the establishment of a Fondo Regulador (regulatory fund) on April 3, 19168. The following day, April 4, 1916, he published a decree creating the Comisión Monetaria (Monetary Commission) to manage this fund and orchestrate the transition6. The Comisión Monetaria was originally run by a prominent group of Carranza's allies: the Minister of Finance, Luis Cabrera; the General Treasurer of the Nation, Nicéforo Zambrano; and presidentially appointed members Alberto Pani, Ignacio Rivero, Carlos B. Zetina, and Carlos Basave. The commission's daily operations were managed by Eduardo del Raso and Francisco Puga.

The first sets of activities undertaken by the Comisión Monetaria focused aggressively on arranging the monetary circulation following the chaos of the revolutionary issues. This monumental task involved exchanging and destroying obsolete currency, officially issuing (and later attempting to withdraw) the Infalsificables, and taking steps to reintroduce metallic gold and silver coins into everyday commerce. To stabilize the money supply and centralize financial power, they also helped the Ministry of Finance wind up private banks of issue, performing credit and banking activities through a newly created network of branches throughout Mexico.

As part of the transition mandated by the July 21, 1915 decree, the government required the public to exchange the previously issued Constitutionalist banknotes—primarily the Ejército Constitucionalista and Gobierno Provisional de México (Veracruz) issues. These older notes were mandated to be deposited and exchanged for the newly arriving Infalsificables at a legally established rate of 10 to 1 (ten old pesos for one Infalsificable)9. Despite this highly organized monetary rollout, the Infalsificables ultimately succumbed to the same macroeconomic pressures of the era, depreciating rapidly shortly after entering active circulation.

The issuance of the 1914 10 Pesos banknote by the Ejército Constitucionalista de México represents a critical intersection of military logistics, sovereign financial policy, and economic survival during the Mexican Revolution1.

To fund a massive, multi-front armed rebellion capable of defeating the entrenched federal army, Carranza faced an insurmountable logistical challenge. Financing a war required vast amounts of capital to procure food, clothing, livestock, and most importantly, arms and ammunition from international suppliers across the United States border. Requisitioning these supplies directly from the civilian populace through force or confiscation was politically untenable, as such actions would incite severe social unrest and rapidly erode the public support required to sustain the revolution

The legal framework validating the creation and forced circulation of this rebel currency was established through a sequence of specific military decrees. The initial legislative authorization occurred on April 26, 1913, when Carranza issued a decree in Piedras Negras, Coahuila. The text of this decree asserted that it was the civic duty of all Mexicans to contribute proportionally to the army's expenses until constitutional order was restored. To enforce this, the decree mandated that all inhabitants of the Republic were legally obligated to accept the Constitutionalist paper money as legal tender, at absolute face value, for all civil and commercial transactions. The decree further promised that once constitutional order was re-established, formal laws would be promulgated to guarantee the redemption of the issued notes2.

As the war expanded, the initial capital injections proved insufficient. On December 28, 1913, operating from Hermosillo, Sonora, Carranza issued Decree No. 14, which authorized a second massive issuance of fifteen million pesos. This legislation was particularly notable because it explicitly prohibited the continued use of alternative local scrip (known locally as fichas, tarjetas, or vales), establishing severe punitive measures for any civilian or merchant who issued or utilized unauthorized localized currency.

The specific legislation authorizing the banknote under review was Decree No. 18. Signed by Carranza on February 12, 1914, while he was stationed in Culiacán, Sinaloa, this decree expanded the money supply by an additional ten million pesos, bringing the total authorized Constitutionalist fiat currency to thirty million pesos2.

The thought process behind the design and physical creation of this specific issue, which eventually became known to the public and numismatists as the "Aguilas Viejas" (Old Eagles) series, was driven by an urgent need for psychological legitimacy. The earliest emergency issues produced by the Constitutionalists (often referred to as the Monclova issue) were poorly printed on low-quality paper and were viewed with deep skepticism by a populace accustomed to the highly secure, beautifully engraved banknotes of the pre-war era2. The leadership recognized that an army could not survive on a currency that looked like a temporary voucher. They required a banknote that possessed a firm, professional appearance and utilized deeply ingrained patriotic motifs to project absolute stability, state authority, and institutional permanence

The 20 Pesos banknote issued by the Comisión Reguladora del Mercado de Henequén, bearing the printed date of November 20, 1914, represents a profound intersection of agricultural economics, military logistics, and regional sovereignty during the Mexican Revolution (1910–1920). To understand the issuance of this fiat currency, one must examine the collapse of the centralized Mexican monetary system. Following the ouster of President Porfirio Díaz and the subsequent assassination of Francisco I. Madero, the nation devolved into a fractured landscape controlled by competing military warlords. The federal banking apparatus ceased to function effectively, and hard metallic currency (gold and silver coinage) vanished from circulation due to extreme hoarding by a panicked public, a classic manifestation of Gresham’s Law.

Faced with a total absence of liquidity required to pay soldiers, maintain government operations, and facilitate basic daily commerce, state governors and military commanders across Mexico were forced to issue their own regional paper money. The state of Yucatán, however, operated under a distinctly different economic paradigm than the rest of the republic. Rather than attempting to back its paper currency with promises of future silver redemption from a depleted treasury, the Yucatán government anchored the perceived value of its currency to its primary agricultural monopoly: henequén. The agave plant, whose fibers were transformed into sisal twine, was a globally strategic commodity. The mechanical grain reapers utilized across the agricultural heartlands of the United States and Europe required massive, uninterrupted supplies of binder twine, rendering the Yucatán economy exceptionally lucrative and highly autonomous

The specific legislative pathway authorizing the 20 Pesos denomination was volatile and shifted rapidly with the tides of war. Historical documentation indicates that Governor Eleuterio Ávila initially expanded the printing limits of the Comisión Reguladora in late 19142. On January 11, 1915, Ávila officially authorized the specific $20 denomination via Decree núm. 57. However, the physical release and forced circulation of the Series C and Series D print runs were orchestrated by a subsequent, rebellious acting governor, Abel Ortiz Argumedo. Facing an imminent invasion by the Constitutionalist forces of General Salvador Alvarado, Argumedo required vast, immediate capital to acquire munitions from the United States

On February 26, 1915, Argumedo enacted Decree núm. 3, officially placing the previously printed Series C notes into immediate circulation. The underlying thought process for the release was strictly driven by wartime extortion. Argumedo coerced the local agent for the International Harvester Company, Avelino Montes, into extending a $500,000 USD line of credit in New York to purchase arms. In exchange, Argumedo directed the state treasury to reimburse Montes with $3,550,000 in the newly authorized Series C and D paper notes. Consequently, the 20 Pesos banknote transitioned from a planned economic instrument into a desperate mechanism of military finance.

The 1915 100 Pesos banknote issued by the Comisión Reguladora del Mercado de Henequén serves as a significant historical artifact of the Mexican Revolution, representing an emergency monetary measure by the short-lived breakaway administration of Colonel Abel Ortiz Argumedo in Yucatán.

Designed to fund local military resistance against the Constitutionalist forces, the note features a portrait of Miguel Hidalgo y Costilla on the obverse and the architectural facade of the Casa de Montejo on the reverse, symbolizing regional identity and political legitimacy. Because the subsequent administration of General Salvador Alvarado systematically demonetized and destroyed this currency upon reclaiming the state, the note—particularly in uncirculated condition—is considered an exceptionally rare and valuable numismatic rarity, prized by collectors for its historical provenance and unique role as a localized economic instrument during a period of national upheaval.

This podcast provides a comprehensive analysis of the 1914 5 Pesos banknote issued by El Banco del Estado de Chihuahua, an institution established by General Pancho Villa to stabilize the regional economy during the Mexican Revolution.

Although commissioned through the American Bank Note Company in New York to project fiscal legitimacy, the shifting military landscape meant the majority of these high-quality, intaglio-engraved notes remained in vaults, never reaching general circulation. Featuring an obverse vignette of a miner with a pneumatic drill and the Mexican National Arms on the reverse, these notes transitioned from revolutionary currency to a unique numismatic fixture, frequently appearing as "movie money" in Hollywood Westerns.

Today, they are primarily categorized as remainders, often preserved in exceptional uncirculated condition for modern collectors.

This academic work serves as a comprehensive doctoral dissertation that reconstructs the history of the Banco de Zacatecas between 1891 and 1916. The text investigates the transition from informal credit systems, dominated by the Church and merchant-lenders, to the establishment of a modern institutional banking framework under the Porfiriato regime. By utilizing a neoinstitutionalist approach, the author explores how legal reforms, specifically the 1897 Law of Institutions of Credit, shaped the bank’s organizational structure, its issuance of currency, and its administrative strategies.

The study provides a meticulous analysis of the local elite and business networks that controlled the bank, highlighting their strategic decision-making and their influence on the regional economy. Beyond simple financial history, the research tracks the bank's trajectory through phases of expansion, diversification into public services, and its eventual seizure and closure during the Mexican Revolution. Ultimately, the work aims to bridge a historiographical gap by detailing how this regional institution operated as both a symbol of modernization and a tool for the consolidation of wealth and power in central Mexico.
