Don, depending on your tax situation, having your heirs liquidate a collection may save a ton in capital gains and state income taxes due to the basis step-up on death. Everyone with a valuable collection needs to assess their tax circumstances carefully before selling any valuable and highly appreciated asset, assuming that there is no need for the money during your life. Why lay out as much as a third in Federal capital gains and state income taxes if you don't have to? Unless things change radically for me, I plan to leave my daughter with a package of cards that she can sell with little or no taxes owed.
I wrote an article on what it is like to sell and how to do it; might be of interest to the OP:
