I have a couple of spreadsheets that provide some guidance. I don't keep them completely up to date, but it will give them an idea that the 1987 Topps doesn't fall in the same category as the tobacco cards.
I'm slowly trying to pare down my actual collection so that they won't be left with a pile of 'stuff' to deal with. But I want them to be aware that there might be some 'value' with what is left and to what extent. What they DO with that is up to them. But I'm at least trying to impart some knowledge.
If I go before my better half, she'll be able to clue them in as to what is junk or not. Ideally if you have someone you want to leave it to, I would advise getting it to them BEFORE you die, assuming you can plan for that.
