The Book on the subject of comic valuation is Overstreet -- you can get a copy at most comic-book shops. It's a pretty thick tome, costing $15 or so in paperback, with prices of all major comic books. If someone wants to go to the effort of properly pricing the things, they should get a copy of Overstreet.
In general, whether it's worth the effort depends immensely upon the age of the comics. If the box has a lot of older stuff (60's and earlier), then it's worth going through it in detail; if it has *really* old stuff (50's and earlier) it may be worth having a professional appraiser look it over.
OTOH, if it's modern (70's and later), then the odds are good that the box isn't worth a great deal. *Most* modern comics are worth a buck or less, in average condition. (Indeed, the majority really are only worth a quarter or so, and are hard to sell.) There are some exceptions, and they might want to have someone knowledgeable glance through it to see if any valuable books are in there, but they shouldn't get their hopes up.
If someone is inspired to inventory the box, and send along the titles and issue numbers, I could give it a quick skim and a ballpark guess of what sort of money they're looking at, and whether it's plausible that they can actually sell it. Or they could show it to a dealer, who might actually be interested in buying...
