It's the Dear Old Queen as she exists on our coins. Apparently, each successive monarch faces in a different direction to the preceding one and that has happened on our coins since King Charles II. He died in 1685 of natural causes, unlike his predecessor Charles I who was beheaded for treason. Gosh, they were violent in those days! Someone once remarked, after the Queen visited Oxford University that it was "the Dear Old Queen meeting the Queer Old Dean (of the University)" - irreverent but funny! Despite what it says, her name is not Reginald or Reg for short. It's Elizabeth and the Reg is short for the Latin "Regina" - Queen to those of us who don't speak the long dead language.
