Hiram Bingham III, best known for rediscovering Machu Picchu, also served as a U.S. politician. However, there is no specific information readily available in the search results that directly addresses his stance on paper money and free silver.

For a precise understanding of his position on these economic issues, it would be useful to explore additional historical records or his speeches/writings if they exist. If you would like, I can conduct a deeper search to find more detailed historical documents or specific references.
