Thank you for contacting Mearto with your appraisal inquiry, and I apologize for the delay. This is a common pattern of American Militia sword common around the turn of the 19th century. There were many different makers of these swords, and they existed at different quality levels. This particular sword is in distressed condition, with significant corrosion present on the blade. It may have had etching and other ornamentation on the blade originally, but it is difficult to say. The brass guard is in good condition, with a healthy dark patina. The bone handle has separated from the brass. Given the condition of this piece, and completed auctions of similar items, a fair market estimation is 225-250 dollars. Please reach out with any questions.
