Hello David.
The GIRO stamps of 1862 are actually some of my favorite revenues.
This information in my scan is from 1915 and the values in the columns are in 1915 French francs.
Giro stamps were for use on commercial receipts and the 'hasta' indicates the 'up to' value for which the individual stamps were applicable.
As annotated at the bottom of my scan in a combo of French and Spanish: The 1 and 5 reales are known with the surcharge REVALUED FOR THE REVOLUTIONARY JUNTA.
I love this series. Hope this helps.
