GUEST: Well, this sort of belongs to my grandfather's great-uncle, the Union Army officer in charge of the hospital at Washington, D.C.

APPRAISER: What you have here is the Model 1840 medical staff officer's sword made by Schuyler, Hartley, & Graham. And the sash, of course, is the standard green color for medical. Retail value of $10,000, possibly $12,000.
