How much is my katana worth?

Excuse me, but I couldn't help but notice your katana. It looks like a beautifully crafted piece, with intricate detailing and a sharp blade. I'm quite curious, as someone who appreciates fine craftsmanship and the value of antiques, how much do you think your katana is worth? Have you had it appraised by a professional? Or perhaps you have some idea of its rarity and historical significance? I'd love to hear your thoughts on the matter.
