The value of vinyl records is still determined by whether you enjoy listening to the music or not. You're not going to get rich from your collection...and that's alright.
From the article, "How Much Are Your Old Vinyl LPs Worth?":

The answer is no.
While some vinyl records may indeed be more valuable than the plastic they're pressed on, Doug Allen, the owner of one of the largest vinyl records stores in the world, Bananas Records in Saint Petersburg, Florida, tells The Penny Hoarder that LPs aren't really comparable to other big-business collectibles, like stamps or coins.
