Its obverse side features La Corregidora (Maria Josefa Crescencia Ortiz Tellez-Giron). Its reverse side shows the bank seal, a bank guilloche, and the Palacio del Gobierno Federal (Federal Government Palace) in Queretaro. The note does not have a security thread or a watermark. The dates and signature on the note may vary. Because it is a used note, it may have minor tearing, folding, and/or ink stains. The note was demonetized in 1984.
