She owns a very old pile of junk, one which could contain various items that appreciated in value from being so old. Bob had an extensive record collection that afaik Chris never sold, and of the 100 or so that survived there's probably a few that have some value. Chris would have a bunch of old toys that became collectors items although they wouldn't be worth jack considering the state they'd be in. In that same vain there might be more old pokemon and Yugioh cards in binders (are old Yugioh cards worth anything idk much about its economy). Of course anything of value will immediately be used to pay debts, so it's not like Chris or Cole are getting any inheritance.
