1978 Mexico Banco de Mexico 500 Pesos P-51t PMG 66 EPQ Gem UNC ABNC Morelos Note

Offered here is a superb 1978 Mexico Banco de Mexico 500 Pesos banknote, cataloged as Pick 51t, and certified PMG 66 EPQ Gem Uncirculated. This is a standout late-date example from Mexico’s classic engraved 500 Pesos series, printed by the American Bank Note Company and beloved for its bold format, intricate intaglio detail, and unmistakable old-school banknote artistry.

Authenticity is fully assured by PMG (Paper Money Guaranty), one of the most respected third-party grading services in world paper money. The note is authenticated, graded, and encapsulated for long-term preservation, and the EPQ designation confirms Exceptional Paper Quality with original paper integrity and superior, untouched surfaces. EPQ is a key differentiator for advanced collectors because it highlights true originality and helps separate premium examples from notes that may have been altered or compromised.

Historically, this 1978 issue represents the enduring final stretch of Mexico’s traditional engraved currency style. Even as printing technology and banknote design began shifting internationally, Banco de Mexico continued issuing beautifully complex intaglio notes with dense guilloche work and strong national themes. As a major denomination of its era, the 500 Pesos carried significant presence in commerce and banking, making a fully original Gem survivor especially appealing today.

The face design features José María Morelos, one of Mexico’s most revered independence leaders, engraved with striking clarity and depth. Surrounding the portrait is an ornate framework of scrollwork, layered geometric lathework, and bold denomination counters that create a rich, textured look under light. The reverse highlights the Palacio de Minería, a celebrated Mexico City landmark, rendered in rich green with crisp architectural detail and balanced symmetry. ABNC’s refined engraving is evident throughout, giving the note that “three-dimensional” intaglio appearance collectors consistently chase.

Catalog identification for this note is Mexico, Banco de Mexico, 1978, 500 Pesos, Pick 51t, printed by ABNC, graded PMG 66 EPQ Gem Uncirculated. The holder also records the series and serial specifics for this exact example, an added plus for collectors who enjoy the finer issue details within the Pick number.
