Peter Jefferson is a taxidermy bald eagle who lived at the Philadelphia Mint from around 1830 until 1836. He became well known after a while and was let out of the Mint each night to fly around the city. While perched on a coining press one day, the press suddenly started, and Peter's wing was badly injured. Despite attempts to save and heal him, he died, and his stuffed body was placed on display at the Mint. To this day, Mint artists study him when working on new eagle designs.
