I no longer speak to the value of carpets on this forum. Valuation requires considerations that are best seen in person. Even with online photos, there still needs to be some form of market reference and understanding of current prices which can take time and research. My objective here is to help inform buyers and sellers.
My opinion is, however, cautious with these rugs for pet stains - also, image quality is quite low, so don't hold this too high:
Rug01 - nothing spectacular, perhaps a few issues to be wary of. Be wary of coarse wool and weave on this piece.
02 - if this is a mohajeran sarouk of age, the shade of light blue border is considered somewhat unique and desirable. some condition issues could be forgiven if this is the case.
03 - sarouk runners have a market price, although careful for anything particularly coarse, or rugs with damage. Also note lower end of the photo shows a slight yellowing which may be of concern. Do not apply significant value to this rug if it has condition issues which are not easily reversible, or lower grade characteristics.
04- clockwise - the far rug under the bed may be a farahan or josan sarouk. Cautious on anything with particularly garish colors, or brittle foundation. the rug to the right is nothing great. the carpet closer to the camera appears to be an early lilihan variety. may be a good rug.
05 - may be a gem. If the asking price is reasonable this rug alone may be worth the trip by itself provided condition, colors, quality and age are what they may appear. The rug should have a thin character and somewhat rigid construction. This would be considered a hard-to-find and unique color and good design carpet - however, it may not be particularly valuable. Gem meaning - it's a diamond in the rough. The market value in my opinion has likely not caught up to the uniqueness if it is what it appears.
06 - blue sarouks are always good, although caution on condition issues or loss of rows to knotting on formal style carpets.
