Most Expensive Books Codex Leicester


Books have been an integral part of human civilization for thousands of years, serving as a means of preserving knowledge, culture, and history. While most books are bought and sold for moderate prices, some rare and significant works have fetched staggering sums at auction, highlighting their importance and the value collectors place on them.

The most expensive books ever sold typically include historical, scientific, and artistic masterpieces, crafted by some of the greatest minds the world has ever seen. Works such as the Gutenberg Bible, John James Audubon’s The Birds of America, and Leonardo da Vinci’s Codex Leicester have commanded prices reaching into the millions of dollars. These remarkable tomes not only represent the pinnacle of achievement in their respective fields but also serve as tangible links to humanity’s intellectual heritage.

Most Expensive Books Ever Sold

Codex Leicester

The Codex Leicester is known as the most expensive book ever sold, with a price of $30.8 million in 1994. Purchased by Bill Gates, this 72-page text was written by Leonardo da Vinci and is essentially his science diary. Adjusted for inflation, the value of the book amounts to approximately $54.4 million in 2021.

Bay Psalm Book

Another record-breaking book is the Bay Psalm Book, which is the first book printed in British North America. Its significance and rarity led to a sales record of $14.2 million in 2013. The book is a translation of the biblical psalms and was created by the Puritan leaders of the Massachusetts Bay Colony. It is considered a milestone in the history of printing and played a major role in the development of American literature.

First Folio

The First Folio, a collection of William Shakespeare’s plays, is also one of the most expensive books ever sold. Officially titled “Mr. William Shakespeares Comedies, Histories, & Tragedies,” it was put together by two of the Bard’s close friends and fellow actors in 1623. In 2001, a copy of the First Folio sold for $6.16 million. This edition is incredibly valuable due to its historical importance and the fact that it is the first complete collection of Shakespeare’s plays.

Notable Auctions


Christie’s has a history of hosting auctions that feature some of the world’s most expensive books. For instance, in January 2014, a 16th-century illuminated manuscript from the region of Flanders was sold for an impressive $13 million at Christie’s. This lavish manuscript was originally most likely intended for the hands of the Netherlandish royal court and is widely considered one of the world’s most valuable antique books.

Another significant sale at Christie’s involved Shakespeare’s First Folio, which set a new record in the category. The First Folio is a collection of the Bard’s plays and is revered as one of the most important early publications in English literature. Its sale further solidified the auction house’s reputation for handling notable and valuable books.


Sotheby’s is another prominent auction house involved in the sale of rare and expensive books. Arguably the most famous book sold at Sotheby’s is John James Audubon’s The Birds of America. In 2010, a copy of this landmark work went for $11.5 million, making it one of the most expensive books ever sold. The Birds of America is known for its life-sized illustrations of North American birds and its meticulous detail, which has made it a highly coveted item among collectors.

Additionally, a significant sale in the realm of Jewish literature took place at a Sotheby’s auction in 2015 when one of the extant copies of the Babylonian Talmud was purchased by New York businessman Leon Black for $9.3 million. This noteworthy sale made it the most expensive piece of Jewish literature ever acquired.

Factors Determining Value


Rarity is one of the key factors determining the value of a book. A book is considered rare when demand exceeds supply, and it usually means there are fewer available copies in the market. This scarcity makes a book more valuable to collectors and enthusiasts.


The condition of a book also plays a significant role in determining its value. A well-preserved book, with minimal damage to its binding, pages, and cover, will be more valuable than a book in poor condition. Factors that can affect a book’s condition include:

  • Presence of markings or inscriptions
  • Damage to the spine, cover, or pages
  • Fading or discoloration
  • Missing pages or illustrations

Historical Importance

Books with historical importance, such as first editions or those containing groundbreaking ideas or theories, often hold greater value. These books may have played a significant role in shaping the course of history, society, or their respective fields, and collectors prize them for their significance and impact.

Cultural Impact

The cultural impact of a book can also influence its value. Books that have resonated with readers, inspired generations, or become iconic pieces of literature are often more valuable than others. The cultural importance of a book can depend on factors such as:

  • Popularity or influence at the time of publication
  • Longevity and continued relevance
  • Awards and critical acclaim
  • Adaptations to other media (e.g., film, television, or stage)

Protecting and Preserving Expensive Books

Storage Conditions

Proper storage conditions are essential to preserve the value and condition of expensive books. The key factors to consider when storing such books include:

  • Avoiding direct light, heat, and humidity to prevent damage and fading
  • Storing books in a cool, dry place, preferably at a constant temperature between 60-70°F (16-21°C) and relative humidity of 40-50%
  • Shelving books of similar height together to reduce stress on their spines
  • Using preservation-quality boxes to keep books protected from excess light and to keep damaged bindings together
  • Storing small to medium-sized books upright (vertically) and large, heavy volumes flat (horizontally)

Handling Practices

Preserving expensive books also involves taking appropriate handling precautions. Some useful practices include:

  • Washing hands thoroughly before handling the books to avoid transferring oils to pages and covers
  • Using protective plastic covers, such as mylar, to protect book jackets and covers from spills, dust, and oils
  • Wrapping older books in acid-free, UV-resistant plastic book covers to prevent damage and fading
  • For paperbacks, using book sleeves made from the same material as the covers
  • Exercising caution when opening and turning pages to avoid damaging the spine and pages

By adhering to these storage conditions and handling practices, collectors can ensure that their expensive books are preserved in the best possible condition for future generations.
