Hello and Welcome to Just Answer,
My name is***** am a Personal Property Appraiser and would be happy to assist you with your question.
A photo would be helpful, but if you can read the maker's marking on the blade at the top of the handle as well as the measurements, it would be extremely helpful in the evaluation process.
Does the sword still have the sheath? Are there any damages? Any pitting, rusting etc?
I look forward to hearing from you,
