Thank you rokujuro. Not to concerned of the value, but at the same time I don’t want to decrease it. I am more into the history of this sword, age being fascinating to me for some reason. I wish the tang was stamped so very badly. Crazy to think that this has been sitting in a friend of mines closet for 30 years or so. He had never researched it, but was special to him because his father gave it to him.
