I have a box of historical newspaper issues from Boston. Would they be worth selling?

I have a box of Boston Globes, and the Boston Herald Traveler (now the Herald) with headlines like the moon landing in 1969, Nixon resigning in 1974, and the Blizzard of '78. How do I tell if they're worth selling, or how to price them? The papers are in very good condition, but I don't really have a lot of use for them.
