500 Pesos 75th Anniversary of Banco de Mexico

Issued to mark seventy-five years since Banco de México's founding in 1925, this note belongs to a commemorative run that sat uneasily between collector piece and circulating currency — Banco de México printed it for both purposes, and examples did turn up in everyday transactions, which is part of why truly uncirculated survivors are less common than the mintage figures might suggest.

The security package — watermark and embedded thread — mirrors the standard production specification for the period rather than anything enhanced for commemorative status. Printed entirely in-house at the bank's own facility in Mexico City, which had been producing notes domestically since the 1960s.
