Is It True That If You Rough Up The Edges Of An Old Penny, It Might Read As A Quarter In A Vending Machiene?

I heard it on a CSI episode. They said that because the older pennies were made with more copper then they are now, they weighed as much as a quarter, and when the edges are scratched on pavement, it could read as a quarter in a parking meter. I was just wondering if this was true, and how this works. Has anyone ever tried it?

How Do Vending Machines Read Dollar Bills?

I know it scans the bill, but what particular part of the bill does it scan?
Some say the face on the bill, others say the numbers in the corner.
Does anyone know the answer with a reliable source?

I dont understand how a vending machine can read money. How can it tell the difference between a 1, 5 or even 10 dollar bill?
