I recently came across a small Beatles collection on vinyl. Is there a service to get them appraised? Check their authenticity/value and maybe sell them at the shop?

There is an app called discogs check it out. It will build a list of your collection as well.

Christian to be honest Beatles Records are among the best selling albums ever. There are quite literally 10's of MILLIONS of them floating around. However if you want to take them to a local authority go see Jack at 4th between South and Bainbridge He's our resident Beatles expert here in Philly

Call them to make sure the owner Jacy is there. He can. Can also check closed auctions on Ebay.
