Hello Ron,
I have read through the post.
This is an interesting rug. I respectfully disagree with Pro's dates of 1910-1940.
In my opinion, this is a 100-120 year old rug, but I do agree with Pro that 150 years old is "a stretch." I agree also with the higher value range Pro made note of.
If this were my rug and I were in your position, I would rely on someone local to see the rug in person.
The gentleman who appraised the rug at $50,000 for insurance purposes: I would ask him how much he would be willing to pay for it.
Replacement value for older rugs is different than newer rugs of this type. My sentiment is the value provided was high, and you'll pay big premiums to insure for this amount.
Additionally, if you were to sell this rug at Sotheby's or Christies, it would go for $7,000 give or take. That's the market as we know it here in the states. If a dealer were to offer this rug at a showroom, asking price may be much different.
All the best,
