Olympic coin covers

I am sure many of you have seen the recent stamps released by the British Royal Mail that are doing the rounds on various design blogs. Whilst the stamps, designed by perennial favourites Hat-trick design, are stunning, combining both athletes and iconic architecture I prefer the simple solution they used for these alternate Olympic coin covers. The simple pixelated designs based upon the Olympic medal shape work really well at this size and I love the contrast between image and stamp/coin. You can view the full set on their flickr feed.
