Matthew 10:29 - 31 New King James Version
29 Are not two sparrows sold for a copper coin? And not one of them falls to the ground apart from your Father’s will. 30 But the very hairs of your head are all numbered. 31 Do not fear therefore; you are of more value than many sparrows.
Read here about the story of the sparrows on the past 1/4 penny, 1/2 penny, and 1 cent coins used in South Africa.
