"I would much rather sell the entire lot all together, I think it would be very difficult for me to sell piecemeal since I don't know what most of it is. "

Understandable but your market is experieced reloaders, not newbies. But new guys tend to want new stuff if for no other reason than they want some assurance they are getting usable stuff and they have no experiece to evaluate used equipment. On the other hand, those of us with the experiece to know already have a lot of stuff, we would only be interested in a a few new other items or to up-grade a few pieces of what we already have. Your grandpa is likely to have a large number of items in that stack that others would never need at all. All that makes selling it as a package much less attractive than it may appear.
