When I worked in a High School the janitor picked up all the pennies and siover coins after break time.
He made £'s during the school year. It seems te small change was too little to other about around the tuck shop.Also some pupils threw them as missiles.
Me...
I see a found coin as a lucky penny and pop it in the door space of my car for luck.Sometimes I leave a coin lying to cheer someone else up......
