Guinea wise

From Mr Vivian Linacre Sir: Having been abroad, I have only now seen your advertisement in The Spectator of 2 June, the text of which ends: 'Complete in its own royal blue case, 470 guineas (or, if you're under fifty, £495.00).'

That is incorrect: 470 guineas = £493.10s Od or £493.50.
