This is an exceptional example of a 1 Peso note from Banco de Hidalgo (1914, Pick S304b), graded UNC. The obverse features an impressive industrial/mining scene with ornate columns and multiple workers rendered in black on yellow-green underprint, while the reverse presents a formal portrait in gray tones—both sides display the crisp, detailed engraving characteristic of ABNC production. The note remains in pristine uncirculated condition with no wear, making it a desirable example of Mexican regional banking currency from the Revolutionary era.

Banco de Hidalgo issued multiple series, and this P-S304b variant with ABNC printing was produced in sufficient quantity to remain common today.
Banco de Hidalgo was a regional Mexican bank that issued currency during the tumultuous Mexican Revolution, when many regional banks operated under government license. The prominent industrial and mining imagery on the obverse reflects Hidalgo state's economic foundation in mining operations around Pachuca, a major silver-mining center, while the formal portrait on the reverse represents the bank's leadership. This note exemplifies the period when regional Mexican banks maintained currency-issuing privileges before centralization under the national banking system.
The obverse features a magnificent central vignette depicting an industrial mining or factory operation with ornate neoclassical columns, multiple workers, and elaborate architectural lighting elements—symbolizing Hidalgo's mining prosperity. The denomination 'UNO' appears in decorative cartouches on both left and right margins. The reverse showcases a formally dressed bearded gentleman in an ornamental oval medallion, flanked by heraldic eagle emblems and scrollwork, representing the bank's authority and prestige. Both sides employ fine cross-hatching and parallel line engraving throughout as anti-counterfeiting measures. The color scheme of yellow-green and black on the obverse contrasts with the gray and black reverse design.
