It will never be for sale in my lifetime so I do not care the value. In fact, when dad gave it to me he said, verbatim “I'm most happy that I was able to give it to you at a point in your life when it would have meaning.” I am only interested in what it is and how to care for it. Your thoughts are appreciated!
Edit: I myself would be extremely uncomfortable driving out a pin in this sword (I am good at what I do but I dont work in a shop). That said, I would have it looked at by an expert if you deem it advisable and have a recommendation.
