This is a cool piece of history. This is a 50 cents Bank note. They were issued by the Western & Atlantic Railroad.  The railroad was owned by the state of Georgia and operated the "General" and the "Texas", which were two locomotives that was involved in the Great Locomotive Chase. During the chase the General was captured by the Federals at Big Shanty, then recaptured by the Confederates near Ringgold, GA.  There has been 3 movies made about this famous chase. So here is a great way to own a neat piece of history. And here is the story that tells a little about the chase:

 It was the importance of the extensive rail system to the Confederates that prompted James Andrews, a Union spy from Kentucky, to attempt a daring effort to disrupt the 138-mile rail line connecting Atlanta and Chattanooga. Along with 19 Union soldiers dressed as civilians, Andrews arrived at Marietta on April 12, 1862. Here, they boarded a northbound train pulled by the General. At Big Shanty, the train stopped so the passengers and crew could eat breakfast. Andrews used the break to uncouple the engine, wood tender, and three box cars from the passenger cars. They then sped off with the goal of damaging as many W&A tracks and rail bridges as possible. Hearing the General steam out, conductor William Fuller and two W&A employees ran out of the hotel dining room and pursued the stolen train by foot for several miles. Ultimately, Fuller would commandeer the locomotive Texas and, joined by Confederate soldiers, finally catch Andrews' Raiders -- a race Joel Chandler Harris later characterized as "the boldest adventure of the war." So this note could of very well been used by one of these passengers of the great chase.
