500 Reales de Vellón Banco de Cádiz

The Banco de Cádiz was one of Spain's provincial banks operating under the 1856 banking law, which briefly permitted a network of regional note-issuing institutions before the Banco de España progressively absorbed their privileges through the 1870s. Cádiz, as a major Atlantic port, had genuine commercial need for high-denomination paper, but circulation of these notes rarely extended far beyond the city itself — regional acceptance was always the practical ceiling for provincial Spanish issues of this period.

The 500 Reales de Vellón denomination was substantial. Few examples from any Cádiz issue have survived in collectible condition, largely because redemption records suggest most notes returned to the bank and were cancelled rather than preserved.
