Condition: The condition of the books is a crucial factor in determining their value. Books that are in good condition, with minimal wear or damage, will be more valuable than those that are torn, stained, or missing pages.
Completeness: A complete set of the 1924 World Book encyclopedia typically consists of 12 volumes. If the set is missing any volumes, its value will be lower.
Rarity: The rarity of the edition can also affect its value. Some editions of the World Book encyclopedia are more scarce than others, and thus more valuable.
Binding: The type of binding can also impact the value of the set. Sets with original bindings are generally more valuable than those with replacement bindings.
Given all these factors, the value of a 1924 World Book encyclopedia set can range from a few hundred dollars to over a thousand dollars. If you have a set in good condition and complete, it is worth having it appraised by a professional appraiser to determine its exact value.
