African Style Basket - Antique

Contacted the Smithsonian and they identifed the basket as African.  Made by a slave or traveler from the Horn of Africa during the Taureg Era?  Told it's a rare and valuable find, but like most museums they would not put a dollar amount on it.  Need a value for insurance purposes, however, will sell if worth enough to pay off the second mortgage so I can get someone to refinance our home which is no longer worth what we paid.
