Unless you can find a true collector of old, out of data and deprecated electronics, I would say not much at all. You will see them listed on eBay for as little as $0.99 or as much as $1000 for never used sealed in box. But those high priced listings often seem to sit forever with no offers There is one listing I know on eBay for a sealed 32GB 3Gs for $6500, but its been listed for awhile now and no takers.
So, you can ask whatever you want for it, and hope to maybe get close to that if you're patient. But most people wouldn't pay much at all for either - they are useful as nothing more than a collectors item stored in the box, and even so, it's entirely possible the battery in that old device has swollen so much its ruined it even as a collectable. And you'd have to ruin its NIB status to find out.
Personally, I'd drop it off at the nearest electronics recycling drop-box site.
