Hi Aaron,

Thank you for contacting Mearto with your appraisal inquiry.
The pointed shape of this icon is often referred to as a "flatiron" because of its similarities to the shape of an iron.
This is one part of a four-panel or quadriptych icon; some large painted wood icons have space for small ones to be inserted or inset along the bottom, or they can stand along as in your example. The iconography of all four combined is pretty conscripted and wells the stories of the Passions of Christ. Your panel depicts, as follows:
Top: The Elevation (Vozdvizhenie) of the Cross.
Left: The Descent (Sozhestvie) to Hades (Resurrection (Voskresenie) of Jesus).
Right: The Ascension (Voznesenie) of Jesus.
Lower Left: The Old Testament Trinity (Troitsa).
Lower Right: The Dormition (Uspenie) of Mary.

It's unusual for these to be sold as just one panel and the market is stronger for fully-intact four-panel icons. As a single piece, even though this has greater age than some of your other icons, it is worth $75-125

Based on the photos and information provided, and subject to examination, this is:

An antique Russian gilt brass and silver Passion of Christ "flatiron" icon
possibly 19th Century
The rectangular panel depicting five scenes from the Passion of Christ
7 by 5 inches
CONDITION: This icon appears to be in good condition
PROVENANCE: Inherited
$ 75-125*
*represents a fair-market value for auction purposes; retail or asking price may vary.

Please let us know if you have additional items to appraise, or questions/concerns, and thank you again for using Mearto.
