Hidden Treasures: The Most Valuable Children’s Books

The average household is said to own 104 physical books. 

But while you – and your little ones – may be accumulating a range of titles at home, they could be silently increasing in value – especially beloved children’s books.  

Early and limited-edition copies of popular children’s stories, often cherished for their sentimental value or to be passed down as heirlooms due to their classic status, can gain significant value over time.  

Homeprotect conducted a study to identify the most valuable children’s books that, if sold, could earn you more than just dust on your shelves. 

We searched for the Penguin top 100 Children’s books on eBay, to uncover the top prices paid at recently ended listings for ‘[book title/series name] book’. In addition, we searched through popular forums to add some ‘classic World Book Day‘ characters to our list. 

Here are the most valuable books: 

1. The Hobbit by J. R. R. Tolkien 

This 1937 classic takes the top spot, with early editions selling for as much as £2,686 on eBay in recent months. 

It was originally sold for seven shillings and six pence, which is equivalent to £22.58 today when adjusted for inflation – a value increase of 11,796%. 

2.   Alice’s Adventures in Wonderland by Lewis Carroll 

Caroll’s fantastical tale can fetch up to £2,228 on the online marketplace.  

Originally sold for four shillings upon publication in 1865, this is the equivalent of spending £27.40 today. This is an 8,031% value increase.  

3. Harry Potter and the Deathly Hallows by J K Rowling 

The seventh and final novel in Rowling’s magical world is the most valuable book to have in your library right now.  

Originally published in 2007, signed editions, nearly 20 years later, can earn you up to £1,485 on eBay.  

4. The Wind in the Willows by Kenneth Grahame 

Originally published in 1908, this children’s novel has gone on to become one of the most well-known tales to reach readers globally, both in print and in an on-screen adaptation. 

While many may struggle to part with this classic, anyone looking to earn some extra money could earn up to £1,000 by selling this all-time classic. 

5. Hound of the Baskervilles by Arthur Conan Doyle 

Completing the top five of the most valuable children’s books is this classic novel written by Arthur Conan Doyle, featuring the infamous detective, Sherlock Holmes. 

Copies of the book sold recently on eBay for £770 – not a bad way to put a few extra pounds in the bank!  

David Joyson, our Chief Customer Officer and home insurance specialist, has these tips for budding book-hunters: 

1. Consider big events like World Book Day- When families dig out classics, this is a great time for people to rediscover stories and seek out collector’s editions of their favourites. 
2. Do your research- When books are passed down from one generation to the next, details can be lost, so their value can be easily overlooked or forgotten. If you think you have a valuable book, it’s worth doing your research to see which editions are fetching a high price, and if yours could be a hidden treasure.  
3. Get a professional review– If preliminary research suggests a book might be valuable, consider a professional evaluation. This will help ensure you get what it’s worth when selling it, and if you’re planning to hang on to it, to ensure you have the appropriate insurance cover.  
4. Check your cover- Rare or collectable books may be covered by your contents insurance. However, it’s always worth checking the specific policy terms with your insurer and letting them know the specifics of your valuable household items to confirm that you have an adequate amount of contents cover, and whether you need to specify any individual items on your policy. 

And the rest: 

Completing the top 10 most valuable children’s books are Eragon by Christopher Paolini (£745), Percy Jackson and the Lightning Thief by Rick Riordan (£670), The Wizard of Oz by Frank Baum (£668), The Lion, the Witch and the Wardrobe by C. S. Lewis (£516) and Charlie and the Chocolate Factory by Roald Dahl (£483).

Methodology 

We searched for the Penguin top 100 Children’s books on eBay, to uncover the top prices paid at recently ended listings for ‘[book title/series name] book’. 

In addition, we searched through popular forums to add some ‘classic World Book Day’ characters to our list. 

Research was conducted in January 2026, based off auction data from October 2025-January 2026. We chose the highest price sold, not including postage and packaging costs.  

Some listings were international, and in these cases, we used eBay’s own currency conversion.  

We replaced any ‘Best Offer Accepted’ listings with the next highest price, because we were unable to verify the amount spent on these books when ‘Best Offers’ were accepted.
