I see this posting is from 2014, so I don’t know who to address this to. I am seeking information on the legal sale of whale ivory and scrimshaw. They have been in my possession for over 45 years.
They were legally obtained and now I would like to sell them. Please let me know how I can go about this legally.
The best place to start would be with a local auction house. Weschler’s Auctions in Rockville, MD. does on occasion sell Ivory from estates. They would be better qualified to provide an assessment and documentation requirements for a sale of ivory.
