2000 Reales de Vellón Banco de Zaragoza

The Banco de Zaragoza was one of the provincial banks established under Spain's 1856 banking legislation, which briefly allowed regional institutions to issue their own notes before the Banco de España consolidated that privilege in 1874. The Zaragoza bank's notes circulated only within Aragon, and their window of legal issue was short — fewer than eighteen years separated authorization from forced withdrawal.

Reales de vellón, the denomination unit used here, were already an anachronism by 1857; the peseta system was being discussed at official levels, making this note a product of a denomination in its last decade of official use.
