Do katanas hold value?

I'm curious to know, do katanas, the iconic Japanese swords renowned for their craftsmanship and historical significance, truly hold value beyond their aesthetic appeal? Are they considered collectibles by sword enthusiasts and history buffs alike? And if so, what factors contribute to their value, such as age, condition, or the maker's reputation? Is there a thriving market for these swords, and what kind of prices can one expect to pay for a genuine katana?
