Thank you for contacting Mearto with your appraisal inquiry, and I apologize for the delay. This is a Scottish dirk likely from the Victorian era, or possibly earlier. It has a more practical design and general wear present that indicates it being an earlier functional piece, as by the Victorian era, most dirks were used more ceremonially. However, this was not always the case. This piece is in overall good condition, with some significant corrosion on the blade. The handle is in excellent shape. The decorative rivets and basket-weave pattern are still present and visible. Given the condition of this piece, and completed auctions of similar items, a fair market estimation is 700-750 dollars. Please reach out with any questions. Bo Stuck
