Here are some factors that can affect the value of a 1929 ukulele book:
* Condition: The condition of the book is one of the most important factors in determining its value. A book in good condition with no major damage or wear and tear will be worth more than a book that is damaged or incomplete.
* Rarity: The rarity of the book is also an important factor. A book that is rare or hard to find will be worth more than a book that is more common.
* Demand: The demand for the book also plays a role in its value. A book that is in high demand will be worth more than a book that is not as popular.
