The Allure of Second-Hand LEGO® Sets

The LEGO Group’s empire is ever-growing and so are its sets. As new sets are launched, older sets are building value for their nostalgic value. Second-hand sets can be a fantastic way of getting into the world of LEGO® sets, with second-hand LEGO® sets being an affordable option compared to newer sets. Alongside saving your hard-earned cash, second-hand LEGO® sets are also great for the environment by limiting the amount of produced plastic through its reuse.

Where to Buy and Sell Second-Hand LEGO® Sets

Ebay, Bricklink, BrickOwl and Facebook Marketplace are fantastic avenues for people to delve into second-hand LEGO® sets. However, each has its advantages and potential risks.

Pros of using Ebay to buy and sell second-hand LEGO® Sets:

  • Easy to navigate to source those rare editions and bargain sets.
  • When buying more than one item, most sellers will ship this to you in one package, often reducing delivery costs.
  • International shipping- meaning no LEGO® set is out of reach.
  • Ebay offers fixed rates, meaning that, when selling, you can look at your profits beforehand.
  • As a seller, you can list up to 150 products each month at no cost.

Cons of using Ebay to buy and sell second-hand LEGO® sets and parts:

  • When a seller has placed their item up for auction, there is no guarantee you will win as a buyer.
  • As with any product, ensure you complete your own research. Remember to read the small print for dimensions and specifications.
  • Double-check the shipping address to ensure that you will not experience a delay in shipping times.
  • If your item sells, Ebay will keep a proportion of the profits.

Bricklink is the world’s largest online marketplace to buy and sell LEGO® parts and sets- both new and second-hand.

              When selling any LEGO® bricks, it is important to check its condition and sets are complete. Look out for:

              • Scratches and imperfections such as dents and bends.
              • Discolouration- if LEGO® bricks have been left in the sunlight.
              • Dirty parts.
              • Other parts mixed in with the collection such as crayons.
              • If selling as a set, make sure that it is complete. Complete sets should include all the original parts and box, instructions, parts bags, stickers and sticker sheets and any mini-figures.

              Researching and Identifying Valuable Second-Hand LEGO® Sets

              Researching and Identifying Valuable Second-Hand LEGO® Sets.jpg

              Many older sets can be sourced from our stores on Ebay, BrickLink and BrickOwl alongside Facebook Marketplace. Rare, retired and limited edition sets can be worth thousands if kept in pristine condition, although not all sets require you to break the bank. Certain LEGO® sets may be more valuable to the owner as a result of the nostalgic memories they hold. Typically, however, older complete sets will bring you more money since they are out of production. The less damage the better, although, as listed above, there are ways to restore LEGO® bricks to their former glory.

              Connecting with the LEGO® bricks Community

              Sharing your LEGO® set finds has never been easier. There are multiple forums and social media groups that can be found at the click of a button, making those unique finds and collections easier to celebrate with people who truly understand. Certain areas even have their own groups for you to interact, trade, buy and sell second-hand LEGO® sets within your local area. Join the WeBuyBooks Facebook Group to be part of our community.

              The Ethics of Second-Hand LEGO® Sets Reselling

              When buying and selling second-hand LEGO® sets, there are ethical considerations to consider. If buying from a private seller, pricing may be an issue. Depending on the method used to source your LEGO® sets, the reliability of the seller/buyer may be an issue. It is key to research where your item is coming from/ where you are sending to before committing to any dealings (using reviews can be helpful to decipher reliability). To make sure you are getting the best deal use the Ebay, BrickLink and BrickOwl sites to compare pricing.
