Oh man! My wife and I have had this conversation a few times, for while my son does some hunting, he is not the hunter nor shooter that I once was or still am. He does not reload anything, and I have so many supplies and equipment for loading 52 different cartridges, casting equipment and molds, bullet swaging dies and equipment, shotgun loaders, high numbers of firearms and customs with all their paraphernalia, etc, etc, etc.
My wife has no idea the value of these items, so I have tried to build a data base of the items and their replacement values, but that can rapidly change in the future. If I go first, my son has the option of his picks, but I don't want my wife to be taken advantage of by the vultures. Like many of you, I have bought my share of estate and yard sales to know how little many people know about the value of items in our sport, and I have purchased numerous items from LGS who took advantage of widows and bought entire estates at some ridiculous prices.
Sadly, my son and his wife never had children, so I don't have grandkids to leave some of these things too.
