19th Century Suzani Embroidery

Antique 19th century Suzani Embroidery, family heirloom over 120 years old which has been in the family forever. It apparently belonged to my mother's great grandmother. It has no maker markings on it but there is a small number 88 in one corner that looks almost calligraphic which could possibly mean 1888. There are also pencil marks on it where they drew the pattern on. My mother had it appraised in the 80's at about $3,000 and I'm wondering what it could possibly be worth today and perhaps would maybe sell it. Both sides are different. One has very elaborate stitching on it and the other is what looks to be possibly a dyed pattern. The fabric on the back is different then the fabric on the front and the border fabric is different as well.
