I admire this design for new British coins, created by Matthew Dent and based on the shield of the Royal arms. It has a unifying simplicity and beauty, as do the best of the Australian coins, especially the 5c, 10c and 20c-designed by Stuart Devlin and in use since 1966. (The 1c and 2c are no longer used, and the $1 and $2 were introduced later.)
