Some good things to think about. There don't seem to be that many dealers that seem likely candidates to handle a valuable estate collection. The one that comes to mind is Doug Saito but if you are younger than Doug it may not work to list him in your will as the person to sell it. I used to belong to the National Model Railroad Association. The local chapter had a provision similar to Dave Viall's coin club and would help dispose of a model collection upon a member's death, usually by auctioning off things at no cost. I suggested a few years back that that would be a valuable thing our club could do to help members and their families.
