This is an old northwest persian rug. It seems to be even wear which is good. This could be a plus or minus - if it has been painted to hide foundation, this is not good.
It looks like the minor border on one end is gone. It also looks like one end needs to be overcast, which could result in loss in doing a proper fix.
If you were to sell on ebay as a private seller with little other related items it may get $400 - 600. If you held out for a while - say half a year - and the rug is clean with no problems to structure or the back of the rug, perhaps 1200. The design is charming, but likely will not speak to many as there is a lot of negative space without detail in somewhat of a crude way for this type. The whimsical nature would speak well to the right collector, but the problem is the missing end which they may not pay for.
