A great find, and possibly worth something to an ancestor to one of the men found on that roster....though I suspect that the historical value will not be accompanied by a significant monetary value. I'd check with the Chickasaw County Historical and Genealogical Society in Houston. No doubt that they would love to have it though no idea if they would or could pay for it.
