I believe 'sino-persian' means it was made in China...if all silk, price around $350 is what I've paid (Ebay), the problem with all silk rugs it they're thin and should be in a low traffic area or hung on the wall. The rug has quite a few white spots which are flaws and makes it not worth as much.

it is be tightly woven (with more than 200 knots per sq. in., and often with 500 or more knots), intricately detailed, closely clipped, and it does have a real silk fringe that is clearly an extension of the rug's structure, not sewn on or sewn into the ends of the silk rug. Artificial silk oriental rugs often have only medium weaves (less than 250 knots per sq. in., and sometimes less than 150 knots per in.), and often have cotton fringe. Good quality real silk Persian rugs always have real silk fringe. The price would be 250$-300$ for that.. :)
