1. The Book of Mormon – $35 million (1830)
Finally, we’ve reached the crowning glory of this list! The handwritten original book that founded the Mormon faith was purchased by the Mormon church in 2017 for a jaw-dropping $35 million.
Dictated by the founder of Mormonism, Joseph Smith, this book is considered sacred by the followers of the religion. This astounding price tag beat the purchase of the Codex of Leicester by Bill Gates bought in 1994 ($30.8 million).
