As we first reported, the estate of the late "Baron" Joseph de Bicske Dobronyi plans on auctioning off the item -- which came into his possession after she left them on a private plane in 1968.
We're told the estate has been contacted by Hansons Auctioneers and Valuers -- the same auction house that handled the sale of Queen Victoria's undergarments back in 2008 -- and they would like to handle the sale.
Victoria's knickers sold for about $9,000 -- the estate hopes Elizabeth II's fetch the same.
