Thank you for submitting your item for appraisal. This appears to be a turkish Kayseri rug, sold through Lapis Istanbul. Kayseri rugs are of good quality in general and art typically sold to tourists visiting turkey. Prices paid on vacation visiting the Grand Bazaar are much higher than the average buyer would be willing to pay at home. This very much applies for these rugs. The estimate is based on auction results of similar rugs of comparable quality sold at auction. There is no measurement for the sentimental value you might attach to it.
