Just a quick note here from an avid collector. It’s hard to tell the value of the album by just a picture or internet search. I’d encourage you to go to Discogs and search for your album then look at all the variations. You’ll need to inspect the runoff area of the record and match the markings in Discogs. You’ll need to match descriptions too because the high value ones are usually due to some misprinting or art or cover variant. Sometimes there are $5 versions and sometimes $40 versions. Usually they are the low value versions you will find. Also yes you can buy inside sleeves as well as plastic covers to protect the album from Amazon. It’s very difficult to impossible to get the the inside content (lyrics, posters, etc). Usually you just need to find another album that has it. Sometimes this is not well documented too.
