The phonograph record - more commonly known as a vinyl record or just a plain old vinyl - became the most common form of musical storage and distribution as early as the 1910s.
They were around when rock 'n' roll exploded in the 60s, when disco took over the world in the 70s, and still find solace today in hipster cafes and the bedrooms of young people trying to be cool.
Their tactile nature, unique sound quality, and beautiful illustrations make them a wonderful thing to not only listen to, but also to collect.
Whether you've been hoarding records since your childhood or came into the hobby later in life, you'll know full well just how satisfying it is to leaf through your stack and pull out a particularly pleasing album.
Especially when you know it's worth a lot of money.
Not all old records are valuable, but some can be worth considerable amounts. For this list, we've taken the median average price of the records in question from the website Discogs and ranked them in order of price in US dollars.
So, next time you're in a thrift store, keep an eye out for any of these - they might just change your life.
10. Led Zeppelin - Led Zeppelin
In 1969, four lads from England unleashed a record that would change the world forever.
Led Zeppelin's self-titled debut release rewrote the rulebook on rock 'n' roll and helped set in motion heavy metal as an established musical genre.
Songs like Good Times, Bad Times, Communication Breakdown, and Dazed and Confused are now standards in the band's canon and still get middle-aged men jumping up and down across the land to this very day.
This album's significance goes some way to explaining why it is so valuable. However, if you want to rake in the big bucks, you need to track down a very specific version of this LP.
On Discogs, a stereo version of the UK release on Atlantic Records with turquoise lettering fetches an average price of $664.73.
According to another source, versions of the first pressing with more specificities are worth anywhere between $1,800 to $5,500 depending on quality.
Naturally, it's not easy to track these records down and there are plenty of forgeries out there, but it's definitely worth checking. And, if your version isn't worth a fortune, at least you own a copy of one of the most important albums of all time.
