Hacienda El Progreso issued its own currency. Workers could be paid in local bills and coins or wages could be kept in ledgers. This example, published in Las Islas Encantada o el Archipielago de Colon (Bognoly and Epinoza 1905:100) is of a registered one sucre note signed by Manuel J. Cobos. The introduction of national coinage and tokens specific to particular businesses was one aspect of mid-19th century modernization.
