Agree with Brandon,Chinese collectors are the reason NCO's and Mantetsu sword price went up.But now,China's economy start to slow down,and people don't have that much money to spend on their hobby,plus Chinese buyers bought enough Japanese sword from US and Japan pass decade ,the market is saturated.
Can't blame Trump on the sword price.
Well,it's good for us collectors now!I think only the mint NCO deserve $1000-1200 instead of $1500-1800.For the copper handle,I think $2000-2500 is fair.Unless it's mint or very low number,then $3000-4000 is acceptable.
