It is supposedly from ww2 but don’t  know much about it.  I’ll appreciate the person who can verify this. 
 

Thanks.

You need to post better photos.  The Nakago (Tang) is upside down and difficult to read.

Let me know if this works for you. And thanks.

Did an edit on the picture that maybe will give a better view.

I would think the signature is - 陸奥大掾三善長道 - Mutsu no Daijō Miyoshi Nagamichi

Might have been brought home from the war, but that's not a WWII sword.  Much older.  Still could have been used during the war, of course.  Better pics of the saya (scabbard) might help, but it looks like a civil one, maybe wrapped like that to protect it?

In the condition this blade is, approximately how much is worth?

you need to post more photos of the entire blade, but from what i can see it looks in bad condition

Mei seems legit, this sword deserves to be shown to real experts (probably the hardest to find outside of Japan).
