Thank you for contacting Mearto with your appraisal inquiry, and I sincerely apologize for the delay. This is a bronze short sword from likely the Eastern Zhou Dynasty (770-221 B.C.) It matches the pattern and silhouette of comparable examples of this era. This is a stunning piece, with most of the characters still clearly legible. There is some degradation of the bronze, and some significant corrosion in a few areas, however, the piece is still fully intact and appears sound. Given the condition of this piece, and completed auctions of similar items, a fair market estimation is 2,100-2,200 USD (2,798-2,931 AUD.) Please reach out with any questions. This is a very special piece!
