Brits! Inspect your pocket change!
This would never fly in America, but it’s good to go among our cousins in Britain. In 2009 they issued a two-pound coin in honor of Darwin Year.

No surprise, as they’re rare: Wikipedia says there are only 3,900,000 in circulation, and another site claims that they’re worth twice their face value, even in used condition. Here’s one side:
Of course everyone who goes to England already knows that Darwin is on all the ten-pound notes. Imagine that happening in the U.S.!
