One fine day in the 1200s, the Danes from northern Europe attempted to invade Scotland. Scottish soldiers were sleeping as it was mid of night. The raiders were bare-footed and because of the darkness, accidentally they were stepped on the thorny thistle flower, which is abundant in Scotland.

They started to shout out of pain and this alerted the sleeping Scottish soldiers and saved them. That day onwards, the Scottish believed the thistle to be a good luck Charm, so as the 6 pence.

- from a coin collector in India who writes, 'Though my 6 pence coin depicts the acorns, the back of some six-pence coins depicts the English rose, Irish shamrock, and Welsh leek. and the Scottish thistle, because it is considered a lucky charm.'
