Rare Copy of U.S. Constitution, Found in a File Cabinet, Is Up for Auction

After the Constitutional Convention came to a close and the complete draft of the Constitution was finalized in 1787, the founders’ last step was to have the document ratified by at least nine of the original 13 colonies, making it binding to the government of the new nation. As part of that process, Congress printed out 100 copies and sent them around the country, John Kaminski, an expert in the document’s history at the University of Wisconsin-Madison, said in an email.
