Not an expert by any means, just a novice here. And I get that the price you have there is to dissuade buyers for the time being. But you have what appears to be a rather large fukure (open carbon blister) where the steel has delaminated on the cutting edge (aka hamon). Anywhere else (and smaller) and this isn't as big as a problem. But on the edge where the hardened steel is, that'd be called a fatal flaw meaning that this blade is essentially dead to serious collectors. It appears there are a few such fukure. It appears the blade is suriage (cut down) which isn't a problem really; it happens over the lifetime of older blades due to the changing laws in Japan, preference of the owner, or for repair purposes. However, the older the blade is, generally the more forgiving collectors are when it comes to fatal flaws.
As for translation, you'll have to wait on people better versed. I cannot read any Kanji at all and rely on the good graces of those here that can.
Those are my two cents. And of course, I could be (and likely will be shown to be incorrect), but its rather hard to tell from the photos of the blade provided. You should take several more of the blade itself up close and as well-lit as possible to really get the best opinion from the experts here as possible. There are guides located in the How To section that ought to help with that.
