many years ago, my grandfather started collecting japanese swords. He managed to amss about 30 or so, including one particular sword, in which the blade was dated as at least 500 years old, and the guard at about 1200. I have no idea what it would be worth, but before he died, he gave it to me.
Before I went overseasw in the Navy, I had a roaring argument with my father. in a fit of pique, he sold my sword. Later he regretted it, but our relationship never really did get over that fight, and I dont have that swoard anymore either......
