U2 press cuttings

I'd like to sell my collection of newspaperarticles, magazines etc. Since I
collected only the U2 relevant part I don't have the complete issues. So
now my big question: what would be the fairest price to make? Would it be:
here are 50 pages (many small cuttings make a big page) and I charge a
certain price or would it be better to weight them, making a price for say
one kilo of articles? Anyone has experiences? Please let me know.

Of course if anyone is interested in the collection please contact me too.

All the best,

Thomas
