I have a small titanium blade from a harrier jump jet engine - how much do you think its worth?

I was given a trophy as an air cadet in 2001 - its a blade from a harrier jump jet engine made of titanium. I was curious as to its value. I am absolutely mince with measurements so I held my mobile phone next to it which is a blackberry curve 9700 - its roughly the same size but its half the thickness. :P - pretty pathetic i know but if you google the phone and imagine it thinner youll get a rough idea lol
