The entry of billionaires into the rare book market significantly influences prices, often removing any limit on how high they can go. A recent example is a copy of T.S. Eliot's "Prufrock" that was listed for $500,000, previously owned by the poet Paul Valéry. This transaction highlights the extreme valuations that rare books can reach, especially in a market where wealthy collectors are eager to find unique acquisitions.

Even if the book wasn't sold, it is likely to resurface at auctions due to its extraordinary value. With a growing number of billionaires seeking rare items, there will always be a demand for these sought-after literary treasures, ensuring that the market remains vibrant and competitive.
