Harry Potter Exhibition - fake shop goods on display

I don't mean fake like in counterfeit, but these display cases are laid out like they are shop windows and are full of props made for the film.

I really wanted to buy some of the money when it came to the real shop but, even though there are piles of it everywhere on display, you can only spend an absolute fortune on a posh set of three in a 'don't touch' kind of case.
