AbeBooks has released a list of the most expensive books it sold last month, a list that includes a $18,500 first edition of Ernest Hemingway‘s  The Old Man and the Sea–signed “with very best wishes” by the novelist himself.

The month also included a $19,314 sale of a handwritten Latin bible from the 13th century, a $9,500 sale of 1930 edition of The Savoy Cocktail Book by Harry Craddock and a $9,000 first edition of The Age of Innocence by Edith Wharton.

Here’s more about the most expensive book of the month: “Mystere de la Vengeance de Notre Seigneur by Eustache Mercade – $20,000 Published in 1491 in Paris by Antoine Verard, this first edition lacks 16 leaves, but only one complete copy is known to exist, in the Bibliotheque Nationale in Paris.  The sale also included a letter by French bibliographer Amedee Boinet, who confirms the exceptional rarity of this book.”
