Hacienda El Progreso issued its own currency. Workers could be paid in local bills and coins or wages could be kept in ledgers. The coins, published in Las Islas Encantada o el Archipielago de Colon (Bognoly and Epinoza 1905:101) were made of vulcanite on the mainland, in Chanduy, by Anacarsis Medina, an old business contact of Cobos.
