I was interested in a sword on Ebay, item 320144175868 .
The sword has tokubetsu hozon papers from 2000. Strange enough there are two hi with kaki nagashi on the sword which don’t appear on the nakago’s picture on the papers.
Clearly, they have been added afterwards. The upper part of the nakago looks repatinated.
What is the impact of this adaptation on the value of the papers?
