Some people buy LEGO® sets for the fun of it, while others actually purchase those because they like the LEGO® Themes featured there. But there are also investors that know how valuable some sets are, based on the LEGO® Theme that they have and other factors. The truth here is that many themes tend to be extremely valuable and they retain or even increase that value in the long run. Believe it or not, there are some LEGO® Themes in particular that are always known to be extremely impressive, and they retain prices more than you might expect. That’s what makes them so different in the first place.

1. Back to the Future

There aren’t a lot of Back to the Future LEGO® sets. That’s why this is one of the most iconic LEGO® Themes out there because you can easily buy this for a very low price and sell it for a profit. It’s definitely worth checking out, and the benefits are among some of the best.

With that in mind, some sets came in 2013 for this LEGO® Theme and now they are worth many times the original RRP. This is why this is one of the top LEGO® Themes you can find out there.

It’s very different when compared to other series out there, and it definitely delivers on its promise and quality. Which is why it’s a very good idea to check it out for yourself. In the end, you will appreciate the experience and benefits.

Out of this entire theme, the Delorean Time Machine (21103) set is widely sought after because it has the iconic car and also the amazing characters as minifigures. It just doesn’t get any better than this, and people are willing to pay a huge amount of money for sets like these, which is exactly what you want as a collector or reseller.

2. Star Wars

Let’s face it, LEGO® has a ton of Star Wars sets, ranging from sets for every episode to something iconic like the Ultimate Collector Series Set for the Millennium Falcon.

It’s an amazing set with a lot of detail, and it comes with thousands of pieces. Needless to say, this set alone is close to $1000 on the market. There are many other sets that include iconic characters which are widely known to be very costly.

And it’s easy to see why, Star Wars is one of the most beloved series in the world and it does push the limits and boundaries in an exciting, new way.

The interesting thing about Star Wars sets is that many of them come as a limited editions. Because of that, this is one of the LEGO® Themes that will always have lots and lots of value.

Obviously, new sets are coming in, but the older ones are getting vaulted and in the long run, you will find yourself amazed by the quality and results provided by something like this.


Detective Comics or DC is also known to have some amazing LEGO® sets. Those that love superheroes love sets related to Batman or Superman and it’s nice to see that we have things like the Batmobile Tumbler set (76240), Batcave™: The Riddler™ Face-off (76183)and a variety of Justice League-related sets.

4. Disney

Another one of the themes that have become a pleasure to collect for lots of people is Disney. The LEGO® Themes can’t be complete without Disney, since this is one of those things that everyone loves.

In fact, there are more Disney fans than LEGO® fans. So it’s a no-brainer to get this type of set because it looks great, it provides a lot of quality, and most Disney stuff usually ends up being very valuable as time passes by.

Some sets like the LEGO Disney castle set are known to be iconic and a pleasure to create and display. That being said, these are also the sets that tend to retire quite fast.

So if you have the opportunity to grab one, then this is definitely the right thing to take into consideration. It’s a very good idea to check it out for yourself, and then pick a themed set you like.

5. Harry Potter

It’s important to note that despite the movie series being over for years now, Harry Potter is still a best-selling LEGO® set. It’s one of those immortal themes that pass the test of time and it’s super fun.

The quality is impressive, and you will be amazed at its great features and the fact that there is a diverse set of LEGO® sets in this theme too.

The Hogwarts Castle (71043) set is known to be hundreds and hundreds of dollars, the same thing can be said about the Hogwarts Icons Collectors Edition (75391), Attack on the Burrow (75980), Hogwarts Great Hall (75954) and so on.

Hey, I am Matthew Mitchell and I am an AFOL from the UK. I have been fascinated by LEGO® since I was a child. My two children are in love with LEGO® and it's because of them that my interest continued to grow, this is how I fell in to the rabbit hole of MOCs (my own creation). 

With every new MOC I saw I became just a bit more addicted to the endless possibilities that LEGO® offers. This led me to creating Belle-Ve Bricks, a platform where talented designers can share their work with the world.

And where we can create together with you, custom models.
