So, turns out we should all be saving our pennies... literally.
A recent ING study has found we lose a combined $466 million a year in loose change, because the majority of us think it's too bulky to carry.
The study revealed Aussies aged 18-34 lose up to $10 a month each in coins.
More than a quarter of people say they hate carrying coins because of the inconvenience and they 'couldn't use 5 cents'.
