Lego Star Wars Force Awakens promo 2
Lego Star Wars video games are all well and good, but there's nothing quite like a classic Lego set. Warner Bros / Lego

Star Wars and Lego are both global phenomenon in there own right and have separately produced some of the most sought-after memorabilia in the history of popular culture. When the superpowers met however, a holy alliance of bricks and studs was born.

Many of the classic Lego Star Wars sets are now discontinued, with some of the vintage build-your-own kits having appreciated in value to the point where it might be cheaper to construct a real-life Death Star instead.

In celebration of Star Wars Day 2016 (May the Fourth be with you, dear reader) IBTimes UK has perused the second-hand marketplaces and delved into Lego's enormous back catalogue to find the most valuable and rare Star Wars sets that money can buy (assuming you have a lot of it).

Lego Star Wars Millennium Falcon 10179

Millennium Falcon – 10179

Released: 2007

Original RRP: £249.99

Current approximate value: £7,000 (new), £3,750 (used)

The pièce de résistance of the Lego Star Wars Ultimate Collector Series with a price-tag that beggars belief. Consisting of a whopping 5,195 bricks and weighing in at just over 10kg, the fastest hunk of junk in the galaxy is the second-largest Lego set ever and is the jewel in the Lego Star Wars crown.

Lego Star Wars Imperial Star Destroyer 10030

Imperial Star Destroyer - 10030

Released: 2002

Original RRP: £342.49

Current approximate value: £3,000 (new), £1,399 (used)

This blocky recreation of the intimidating Imperial craft clocks in at over 3,000 pieces, providing the level of scale necessary for the iconic triangular battleship. Lego fan-site The Brothers Brick note that the minifigure-free, mammoth vessel is "frequently used as a scale reference for very large Lego fan creations".

Lego Star Wars Rebel Blockcade Runner 10019

Rebel Blockcade Runner (Tantive IV) – 10019

Released: 2001

Original RRP: $199.99 in US

Current approximate value: £2,000 (new), £1,000 (used)

While the Imperial Star Destroyer includes a to-scale Tantive IV for those with a burning desire to recreate the opening scenes of A New Hope, purists will likely fancy this much-larger version of the Rebel's Corellian vessel as well. Leia's Corvette model ship is incredibly rare and can also lay claim to introducing a new 'dark red' brick into the Lego tool-kit.

Lego Star Wars Death Star II 10188

Death Star II – 10143

Released: 2005

Original RRP: £249.99

Current approximate value: £2,400 (new), £1,300 (used)

More of an architectural marvel than an actual play-thing, the Empire's second attempt at creating a planet-annihilator makes for a rather functional Lego set. Packaged with a display stand, this one is for the artistically minded collectors out there.

Lego Star Wars Cloud City 10123

Cloud City - 10123

Released: 2003

Original RRP: $99.99 in US

Current approximate value: £2,000 (new), £700 (used)

Lando Calrissian's floating city of Bespin is one of the smaller classic Star Wars sets, but where else can you find a "working" carbon freezing chamber? With four distinct "play areas" and a star-studded mini-figure collection, you would be hard-pressed to have a bad feeling about this minimal set.

Lego Star Wars Super Star Destroyer 10221

Super Star Destroyer – 10221

Released: 2011

Original RRP: £349.99

Current approximate value: £1,600 (new), £600 (used)

Darth Vader's personal flagship and the Imperial command centre in The Empire Strikes Back and Return of the Jedi, the Super Star Destroyer is quite the spectacle in Lego form. The hilariously diddy Star Destroyer that comes in the box shows off how grandiose this gargantuan, 3,152-piece ship really is.

Lego Star Wars Rebel Snowspeeder 10129

Rebel Snowspeeder – 10129

Released: 2003

Original RRP: $129.99 in US

Current approximate value: £1,400 (new), £700 (used)

Surprisingly, the sleek, AT-AT-toppling Snowspeeder is rarer than its space-based brethren the X-Wing Fighter. As one of the early entries in the sought-after Ultimate Collector Series, the Snowspeeder unfortunately doesn't include a minifigure for Luke Skywalker's short-lived co-pilot Dak Ralter. Poor Dak.

Lego Star Wars Motorized Walking AT-AT 10178

Motorized Walking AT-AT – 10178

Released: 2007

Original RRP: £89.99

Current approximate value: £600 (new), £200 (used)

It's not the most expensive set on the list, but the clue to why you would want one is right there in the title. Actually the second version of the hulking quadruped snow-tank, this walking All-Terrain Armoured Transport battery-powered set is quite rare, but the open-top cockpit and grappling line for Luke's classic lightsaber take-down make it worth the asking price.

Lego Star Wars Death Star 10188

Death Star - 10188

Released: 2009

Original RRP: £274.99

Current approximate value: £500-£400 (new), £250 (used)

You can safely mark this multi-faceted set out as 'one for the future'. Combining bits from the that's-no-moon space stations from both Episode I and Episode III, this incredibly popular Death Star includes a massive 24 'minifigs', a multitude of moving parts and classic set-piece areas like the trash compactor and the Emperor's Throne Room. A fan favourite which, if you do a bit of internet detective work, you can still buy for a reasonable sum – in Lego terms at least.
