500 Lempiras

The 500 Lempira note was introduced as Honduras's highest denomination during a period when persistent inflation had effectively made smaller notes impractical for large transactions. Oberthur Fiduciaire, acquired by François-Charles Oberthur in the nineteenth century and one of the older surviving security printers in the industry, handled production throughout the series run.

Cotton substrate with watermark and embedded security thread places this squarely in the mid-tier security specification — adequate for regional circulation but below the polymer or hybrid specifications Honduras later considered for lower denominations. The series ran for seven years without a major redesign, which is a reasonable indicator of stable production arrangements rather than any particular monetary disruption.
