The museum, owned and operated by the non-profit Coffeyville Historical Society, is the realization of a dream of many Coffeyville citizens who understood the importance of collecting items not only relating to the Dalton Raid but also relating to early-day life in the Coffeyville area.  In the museum, which is just east of the Plaza area, are collections of the following:

- Mementos of early-day Coffeyville
- Mementos of Wendell Willkie - who lived and taught school in Coffeyville
- Mementos of Walter Johnson - who lived in Coffeyville
- Mementos of the Dalton Raid
