There is a more serious question here, why did you spend £470 on a camera for your Mum when she was never going to use it? £470 would have gone a long way to paying for a Le Mans trip! If not paid for it all. You need to get your priorities right!
And whilst we are all bashing Kev, can you please get rid of that irritating graphic!
Anyway, to answer your question, I haven't got a clue, but you might find that the component parts are worth more than the whole, I guess you need to research somewhere like eBay to see what the stuff actually sells for.
