In the age of Netflix and Amazon Prime, your DVD and Blu-ray collection may appear to be nothing more than a relic of a not-so-distant past. But some of the films and TV shows in your collection can prove surprisingly valuable. From Cliff Richard's take on Wuthering Heights, to 60s TV dramas and Harry Potter box sets, here's how much some are selling for.  

British pop singer Sir Cliff Richard played the eponymous lead in his own musical version of Emily Brontë's Wuthering Heights back in the 90s. The stage version, which centres on the title character and was applauded by Richard fans but less welcomed by Brontë-ites, was then filmed and released on DVD at a list price of $25 (£20). Rare copies are currently being sold on eBay for up to $50 (£40). 

The supernatural horror comedy film series The Evil Dead was a hit during the late 70s and 80s, and got a reboot with a fourth film in 2013.

Lovejoy was a BBC comedy drama originally broadcast during the 80s and 90s that centred around an antiques dealer played by Ian McShane.

It is currently available on eBay for $89 (£70).

Rags-to-riches tale Scarface starring Al Pacino and Michelle Pfeiffer made $44 million at the box office when it was released in 1983, despite concerns over the amount of violence.

The Forsyte Saga followed a nouveau-riche English family and is often cited as being the first TV miniseries. First broadcast by the BBC in 1967, it became a massive hit around the world including, unprecedentedly, in the Soviet Union. The 2004 The Forsyte Saga DVD Box Set (RRP $87/£70) is selling on Amazon for up to $115 (£90).

Valuable US records you might have at home

Set in 2035, science fiction action film I, Robot starred Will Smith as a robophobic cop investigating the death of a robotics professor which may have been caused by one of his own creations.

An unopened version is currently listed on eBay for a mighty $350 (£275).

Younger generations probably best know Dick Van Dyke for his roles in Mary Poppins and Chitty Chitty Bang Bang, but in the 60s he was famed for US TV sitcom The Dick Van Dyke Show.

Broadcast between 2004 and 2010, it was tricky to explain the plot of the US TV series Lost to the uninitiated.

If you've given up trying to work out what was going on, the Lost: The Complete Collection Limited Edition Blu-ray Box Set (RRP $280/£225) is selling on Amazon for as much as $387 (£311). While a DVD set of the series with an accompanying Senet Board Game (RRP $271/£218) is currently on sale for $391 (£314).

Given the scale of the fanbase, it's perhaps unsurprising that the Harry Potter franchise is behind two of the most valuable sets of DVDs and Blu-rays.
