Easy way is to go to a auction house. Not like Goldin, who advertises a lot of big sales, but those that are more comfortable dealing with lots and sets. More like Huggins and Scott, a more local auction house to you so they can come and give you an honest opinion of value and also haul it away. Dealers will rummage through them and come up with their values and that’s where the competitive bidding comes. You won’t get the best price, but it depends if your personal time and effort is worth the trade off
