2011 London Olympics Aquatics (first design)

This coin that represents the Olympic sport of Aquatics is considered to be the 27th rarest in the set.
The designers originally created the reverse side image to show more water and wave lines. There were several Aquatics 50p coins minted with the lines in the image of the water going through the face of the swimmer before the design was withdrawn and changed so that the swimmer’s face is more visible.
