I have a document I prepared in case I eat it, for my wife with all sorts of information in it. About once a year, I audit my gear's approximate market value for each piece and update it. That can give her some good information on what she has and what it's worth. From there she can decide if she wants to sell it as a whole or part it out.
Knowing her, she'll probably sell it as a whole for less $$ and move on since she'll have much bigger issues to deal with than this stuff.
