The price range for a katana can vary widely depending on several factors, including the quality, craftsmanship, age, historical significance, and reputation of the swordsmith. Additionally, factors such as the materials used, construction techniques, and any accompanying certificates of authenticity can also impact the price.

For a newly made, entry-level katana of decent quality, prices can start around a few hundred dollars. These swords are often mass-produced or made by less renowned swordsmiths and may not have the same level of craftsmanship or historical significance as higher-end pieces.

As you move up in quality and craftsmanship, the price can increase significantly. Authentic, handcrafted katana swords made by renowned swordsmiths or belonging to historical periods can range from several thousand dollars to tens or even hundreds of thousands of dollars. These swords often hold significant cultural and historical value and are crafted with meticulous attention to detail and traditional techniques.

It's important to note that purchasing a katana is an investment, and the price should reflect the quality and authenticity of the sword. It's advisable to seek reputable dealers or consult with experts and collectors in the field of Japanese swords to ensure that you are making an informed decision and obtaining a sword that matches your budget and expectations.
