Dear Leslie,
Your rug is an antique handwoven Persian Kashan. Based on its age it would be considered to be in fair condition. It dates from the late 19th to early 20th. Located in the Isfahan region, Kashan is one of the oldest cities in Iran. Rugs from this area gained popularity in the 19th century with the influx of western tourists. These pieces are known for the unique center medallion with its palmetto style leaves and arabesque designs, which are surrounded by a bright red background. Based on recent price valuations for pieces similar to yours in style, size, and condition, the fair market estimate would be between 500 to 1000US dollars.
Best Regards,
Morgan
