Hi Kay,

Thank you for contacting Mearto with your appraisal inquiry.
If you'd like for your appraisal to include dimensions, which is customary, please forward in the comments section - at your convenience - the overall height, height of the seats from the floor, and the width to the outside of both arms...and I'll update this ASAP.
You are indeed correct about these chairs being from the 19th Century; in this case, they were part of a style movement called the Spanish Colonial Revival, which looked to art and objects made in the 15th and 16th century in Spain for inspiration. Regretfully, the market for Spanish Colonial Revival things is pretty soft at the moment, but these chairs have a handsome stature and are in good condition, all of which is beneficial for their value.
Based on the photos and information provided, and subject to examination, this is:

A pair of Spanish Colonial Revival walnut and leather upholstered open armchairs
made by the Banco Central de Reserva del Peru, late 19th Century
Each with straight stiles terminating in scrolled "ears," the rectangular backs with brown leather upholstery with nailhead trim, gently shaped arms ending in scrolled terminals over a trapezoidal seat upholstered in brown leather with nailhead trim, on shaped front legs, all joined by a box stretcher. Unmarked.
