Years of issue:
The 1972 crown was the first British coin to have a face value of 25 pence. Previous crowns had been Five Shillings face value. Also, for the first time in modern times, the obverse did not incorporate a date, but merely bore the Queen's name and titles surrounding her portrait. The reverse features the letters E and P to represent Elizabeth and her husband Philip, surmounted by a crown and set amid the heraldic flowers of the United Kingdom. The names of the couple appear at the top, with the anniversary dates at the foot.
