Is there a way to figure out if old albums are worth anything?

I was at my moms the other day going through some old boxes and she has several boxes chock full of old vinyls and some 45s. Most are utter junk but there was some Beatles, zeppelin, dylan, fleetwood mac, etc that I figured may not be total crap. All are definitely originals that were purchased in the 60s or 70s.

Is there a way to get a sense on if these are worth anything? My first thought was to simply google or check ebay but it's hard to glean anything there because some show a range of like $15 - $2K so that's not helpful. Also I know I haven't uncovered some rare hidden gems so I'm not expecting anything like that. I didn't know if there was a website or something I could reference that may be more helpful.
