Pete Smith Stereoview Collection

Stereoviews of the U.S. Mint, Treasury, and Bureau of Engraving and Printing.|Intended to be viewed via a stereoscope, these stereoviews created an illusion of three-dimensional depth from a pair of two-dimensional images. Many numismatically-themed stereoviews were produced in the early 20th century by Underwood & Underwood, Keystone View Company, and others.
