The National Numismatic Collection at the Smithsonian's National Museum of American History is the largest collection of numismatic artifacts in North America. It features more than 450,000 coins and 1.1 million pieces of paper money spanning nearly 30 centuries. In addition to showcasing artifacts of payments past, the curators are also interested in documenting how the way we pay is evolving today specifically around cashless transactions. And we're excited to announce that Square Reader will be included in this effort as part of the museum's new exhibit "The Value of Money," which opens this summer.
