PRICE GUIDE: Agatha Christie First Editions

Updated: July 2024.

The first step in determining the value of a book is to confirm it is actually a first edition - whether a global first or a national first. For insights on identifying firsts, please see our series of articles on this topic which can be accessed via this link.

Values as of 2024.

The value of an Agatha Christie first edition is heavily influenced by condition. The difference between a "Near Fine" dust jacket and a "Good" jacket is vast. This is exponentially true for books published in the 1930s and earlier. All prices provided are based on the book and jacket being in "Very Good" condition (complete and free from substantial flaws, such as damage, missing pieces from the jacket, frayed cloth etc.).

Values show below are heavily influenced by actual auction prices realised within the last few years. If the book sold was 'Very Good', then that's a dominant determinant in my valuation. If it was lower quality, I use the price as a guide and extrapolate as fairly as I can. I do not include any signed books in the assessment. Because there are so few examples of 1920s 'Very Good' auction books, especially so in dust jackets, I've had to estimate many of these.

In general the best indication of value is to examine recent auction results. For books from the 1950s and later, eBay is the best resource for prices realised and their database is easily searchable. Pay particular attention to the visuals, not just the text. eBay is rife with inaccurate descriptions - both in grading and actual book points. For books from the 1920s-1940s, auctions remain the best indicators of true market value.

Signatures:  Valuations will increase significantly when signed or inscribed. An authentic signature will generally add £500-1,000 in value. An inscribed copy to a close connection of Christie's will command more, but value will be determined through the eyes of the buyer. Before buying any signed item, please read our article on 'Fake or Fortune' (link).

In the tables below I provide valuations in British Pounds of both UK and US first editions. Prices are provided for the book if it lacks a jacket, and then for a book with a jacket. Ultimately, the value of a book should be a price at which a willing seller and a willing buyer can agree. No assurances, guarantees or actual valuations of a specific book are being provided. This is informational only and a guide to the current state of the market.

1920 - 1929.

1930 - 1939.

Future updates will include valuations for books from the 1940s onwards. For now, please use the auction results below as a guide.

Notable Auction Results from the Last Few Years.

Recent significant auctions of Agatha Christie have been as follows:

5-September-2019 at Heritage Auctions in the USA.

4-February-2021 at Sotheby's in the UK.

2022-July: Heritage Autions in the USA.

2023-September: Christie's Auctions in the UK. The Charlie Watts Collection (mostly signed).

2024-February: Forum Auctions in the UK.

To learn more about these auctions and the prices realised please go to this link. Here you will find details on the lots and prices realised. A few of these auction prices can also be seen below. Note: I do not generally include signed books as prices are harder to extrapolate into the market.

Prices References:

HA19: Heritage auction on 9/2019. Books and jackets were generally above average.

SB21: Sotheby's auction on 2/2021. Books and jackets were generally above average.

HA22: Heritage auction on 7/2022. Books and jackets were generally of a slightly lower quality than HA19.

Generally, domestic books sell better at domestic auctions (i.e. UK books at a UK auction). Buying across markets - a UK book at a US auction or vice-versa - generally offers better value for money. This may be the shipping and customs hassle effect. Most collectors of US books are in the US, so buying in the UK poses more logistical challenges.

Condition: Generally, all books and dust wrappers from the Heritage Auction were in 'near fine' condition, though a few had some restoration or chipping. The Sotheby's auction had significant variance in jacket quality. For full details on that auction click here. Books or jackets / wrappers of poorer quality certainly detract heavily and thus significant price reductions should be expected. Books not listed were not at either auction as there were no reserve items, or were sold in multi-book lots (so hard to confirm individual value) or realized values under $500.

Notations: Prices reflect a 'very good' jacketed copy with no major flaws unless noted. Common observations are abbreviated with one of the following notations:

(bk): Book only, no jacket.

(F-dj): Fine dust jacket - one that is exceptional for its age and most uncommon.

(G-dj): Good-only dust jacket, thus with numerous flaws, damage or missing pieces.

(L-dj): Later state dust jacket. If the version is none, it will be noted.

(s): Signed only, or signed to an unknown person.

(i): Inscribed - i.e. signed to a known person or with unique comments.
