Need help for some woodblock prints

Hello, I found these woodblock prints in a local estate sale. The seller want about 50 each.

I wonder if anyone could give me some guidance about the age, artist, and most important the market value? Thanks!

The first five are by Utagawa Kunisada.

 

I like the guy walling up his dead enemy........shades of E A P.....

 

50 dollars?, 50 cents?, 50????

I have a hard time selling such block prints at any price regardless of age, condition, or general desirability in a greater market. Unless you have a sure market, you need to be careful.
