It depends mostly on knot count and condition. Higher knots per inch, the higher the price. Silk (instead of wool) makes the price 3-4x higher. A fairly low knot count (about 100 kpi) Shiraz rug of about that size would run somewhere between $1300-$5000 most likely. If you hunt around I would expect a "great deal" to be ~$1000. Here's an example of a Shiraz-style rug with 140kpi. http://esalerugs.com/red-5x8-shiraz-lori-persian-rug-110905317 http://esalerugs.com/red-5x8-shiraz-lori-persian-rug-1109053... Once you get into higher knot counts (300+ kpi) the price increases very quickly as well. But I personally think it's important to see what that knot count difference looks like in person. There's a very big perceptual jump in quality and it's almost like going from 8-bit graphics to modern 4k in terms of how the design looks. An example: Here's a 150kpi Kashan rug $3300 http://esalerugs.com/red-10x13-kashan-persian-rug-110909188 http://esalerugs.com/red-10x13-kashan-persian-rug-110909188 and a 400kpi Kashan rug of similar design $13000 http://esalerugs.com/red-10x13-kashan-persian-rug-110906616 http://esalerugs.com/red-10x13-kashan-persian-rug-110906616 It's very hard to tell across the web, but 400kpi compared to 150kpi is night and day. I've seen high knot count silk rugs that were easily in the six figures.
