The box of .303 Savage likely will pick up 50 bucks or better on its own. Hasn't been made for a coon's age, still lots of old rifles around.
I've got several boxes of those purple shells (12 gauge) in AAA and SSG, they are great ammo but I don't hunt deer with buckshot and, of course, they can't be used for migratory anymore - so, what to do with them? The AAA was very effective on geese back in the day.
