Approx cost of REALww2 Japanese items like sake cups, canteens & swords?

[curio bill]

I have been browsing a certain sales website that shall remain nameless & was wondering, What is the approximate cost one should expect to pay for a legitimate REAL ww2 japanese sake cups, canteens and/or machine made NCO shin gunto swords?? I know MOST of the swords there will be chinese made fakes, but I did not expect the sake cups & canteens to be fakes. thanks, Bill
