The Smithsonian Institution is seeking volunteers at its transcription center to create digital images for online illustration of items in its museums, which includes the National Numismatic Collection at the National Museum of American History.

The current focus involving the National Numismatic Collection is to digitize the thousands of certified proofs for paper currency.

According to https://transcription.si.edu, "Since 1863, certified proofs allowed the Bureau of Engraving and Printing to examine every intaglio printing plate before it was placed in production." 

Each certified proof is being cataloged and digitized, with appropriate descriptive information added to each image that will be posted online.
