Uncanny X-men run pricing question

[chromium]

For the last two months I have been selling off the bulk of my 1990 - 2000 comics collection, main reason is make room for more Silver and Bronze

 

Now a local guy has shown interest in My Uncanny X-men series.

 

I'll probably keep #94 through to #200 but sell the rest in lots.

He would like to buy a 50-issue run each month until his money runs out

Trouble is that I don't have a clue what to charge for the runs....

All books from 300 upward are unread (never had the time) all books from 200 upward have been read once. This guy doesn't care about grade, although all books were bagged from day one and probably all fall in the Vf to NM+ grade...

 

so any idea price wise for :

 

#400 - #350

#350 - #300

#300 - #250

#250 - #200

out of all those keep 266, burn the rest. Tata
