Can I first ask you to reconsider using direct load again as it throws up a lot of pop ups. It is a very pretty rug and I am assuming that it has no silk highlight. I am pretty certain that it is not 100 years old but about 50 at a push. It is certainly pre revolution. As for value, these pieces are not so much in demand even though this one is a pretty one. As you might know there are different values one can give. Auction, retail or replacement value. In my opinion the replacement value of this piece is $5000.
