Authoritative price guide for stamp collecting?

I'm looking for an authoritative price guide for postage stamps, primarily US stamps from prior to 1960, similar to the Overstreet guides printed for comic books. There are a number of such stamps I would like to look up.
Online would be great, physical guides that need to be purchased would be fine too. Thanks in advance.
