The Great Gatsby remains most valuable first edition of a 20th century classic

The Hobbit, Ulysses and Casino Royale also make the top ten on a new rare books index

The Great Gatsby remake stars Carey Mulligan and Leonardo DiCaprio

The Great Gatsby remains the most valuable first edition of a 20th century classic, according to a dealer’s new index.

F Scott Fitzgerald’s quintessential jazz age novel is priced at £246,636 for a pristine condition limited edition from the first print run in 1925, with original dust jacket.

London-based dealer Stanley Gibbons compiled the index of 30 first editions, set to launch this week. It includes books such as Animal Farm by George Orwell, Ulysses by James Joyce and the second most valuable, The Hobbit by JRR Tolkien.

The difference in value between The Hobbit and The Great Gatsby is, however, marked. The Hobbit is worth £65,420, double what it was valued at two years ago.

Ian Fleming’s Casino Royale, Tolkien’s The Lord of the Rings, AA Milne’s The Christopher Robin Books and Ayn Rand’s The Fountainhead also feature in the index’s top ten.

The General Theory of Employment, Interest and Money by JM Keynes is the only non-fiction first edition in the top thirty, with a value of £6,820.
