About 20USD is what I would value them at.
Since they're not stamped by a maker with an official makers mark, they would be worth about as much as brand new chinese made ones sold on Ebay that have a somewhat japanese looking inscription. Those are not poor quality despite the origin and I've used mine for a decade now with no complaints, but yours are second/third hand, with an unknown maker and unknown age, unfortunately that doesn't make them collectors editions or highly sought after tools.
Pots though, those could rake in some dough. Even without makers mark, the fact that they're old and patina'd would increase the price a couple fold.
