The Kerman Rug, now having an update on the knot density and closer view of the colors, kilim, etc. I feel more comfortable saying this is a rug from the 1950's. It does appear to be of the much higher grade Kermans which were produced during this time. Many of the lesser qualities would have less knot density, usually hovering in the area of 180 or so. This rug does have higher than that. In most rugs, this difference would be somewhat nominal, although in a Kerman it would make a significant difference. However, this does bring us to the actual value of the piece itself.
Although one of the characteristics of this rug is the higher knot count, the bottom line is in regards to value, anything which is paid would be in aesthetics, and aesthetics alone. There are some dealers who wouldn't mind having this rug for patch purposes, they would not be the ones to pay high dollar. The most value to this rug would be selling it as is, how it is, especially given that it seems to have a decent, newer selvage job. I am unsure how long this rug has been on the stairs for, however, it is important to note that rugs which have been on stairs for extended periods of time tend to wear very, very uneven. The rug seems to have pretty good pile, although I cannot say this for certain. As to the value, I would be upfront as you had mentioned before. In fact, if you state the rug is a "fragment" "remnant" or "reduced" rug, you may get some keyword hits on eBay which otherwise would not have come through. I don't think you're way off with the figure of $400, but it may take some time for the buyer to come around. If overall the rug is in great condition, and looks the same on the top as it does on the bottom (the images we saw) with no uneven wear, I think you could ask $600 negotiable. After all is said and done, you still have to bear in mind one of the most alluring things to Kermans back in the day were the Medallions, and this piece does not seem to have one. It sounds stupid, but even to have the surging done on the edges as this rug has can be an expensive proposition. Although the rug does have an off center pattern, there are people who do not mind this, and additionally, this may be a rug which some would find to be an excellent candidate for tea-washing,
golden washing or other. A lot of information here, but again, part of this depends on what you paid, how you play your cards, and other. If this rug were in perfect condition and the "average" design which would be expected, some dealers would ask upwards of $80 per foot in NEW untouched condition just because of what it is and the vintage. If the colors were better, some would want up to $120 per foot in brand new condition, full, unrestored, untouched.
Actually, I think the best way to approach the sale of this rug would going at it from several directions. List it locally on CL and eBay with
verification. See how it goes over the course of several months. It may get some interest, it may not at all. This also depends on your location. I am unsure of where exactly you're located, but if you're close to a city, you'll probably get some decent exposure on CL. At the same time, if you have an eBay account with a "store inventory," (I believe this is a $15 a month fee with no less than 10 feedback) try listing it in there for the standard 30 day period with an asking price of a little more and include a "best offer" option and see what kind of takers there are out there. It's not worth starting a store inventory for this rug specifically, but it you already have one, it's a good way to keep costs down because store inventory fee is nominal. The colors in this rug are not particularly popular right now, so if I were you I would be willing to settle for a less than the $400, but you never know what may come up or what kind of interest there may be. I would say private party, ideally this would be going for half that, but again, someone may find this to have high aesthetics. If all else fails, after several weeks of accumulating some hits, send it to "fixed price" with "best offer" for 7 days, get some watchers. If it doesn't sell or get any offers, after the item ends send it to no reserve a couple days later and be ready for whatever may happen. Bottom line, it all depends on how quick you want to sell it, and most often the case, the longer you hold out on something with aesthetic value, the closer to your asking price someone may get... Although this could have diminishing returns if you have to hold out too long with having one decent offer turned down....
The last rug I would be more than happy to respond with some insight, but would it be okay if you would create a new thread for it?
