The Royal Mint[1] is to celebrate the 200th anniversay of Darwin's
birth and the 150th anniversary of the publication of On the Origin Of
Species with a special coin.

Am I the only one to think that putting his image face-to-face with
that of a monkey shows a lazy lack of originality? Darwin's ideas were
sparked by examining finches and giant tortoises, not monkeys. A finch
would have been far more appropriate if an animal had to be included.[2]

The general public might readily associate Darwin with apes but this is
surely the opportunity to correct that misconception not reinforce it?

Disappointed of Tunbridge Wells.

accompany his head lest people be confused as to which represents the
monarch.
