Wow!
In April 2011 a Library patron found an 1862 dollar bill in a Winona County District Court civil case file. The case file itself is routine, so the real treasure is the dollar bill. The well worn dollar bill was probably sent to the court to pay for a court fee, but for some unknown reason remained in the file. The case files for this time period are tri-folded, and most likely the file has not been opened and used since 1868 when the case occurred.
