Thank your for submitting your item for appraisal. This appears to be a japanese Katana of the 19th century. Some of the incised characters are difficult to read, I assume "白彦國京乍" There is no date to it. The overall condition of blade, Tsuba and leather scabbard seems to be in good.
Similar items sell in the price range listed above. Asking prices in the japanese trade are near the high estimate.
