What’s it got in its pockets?

For reasons best known to my brain I’ve become fascinated by the new UK coinage in which each coin is a circular section out of a larger image.

Specifically I’m interested in the fact that I’ve still only seen 1p, 2p and 5p coins. Is this just brownian motion in action? Are there so many more of these coins compared to the others? Are the higher denominations simply not out yet? Is it because I live in The North where civilisation frays at the edges? Are you all hoarding them?

This calls for a poll. Which of these new coins have you actually seen?

Enquiring minds need to know.
