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

December 22nd, 2009 Posted in Información General

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?

    Says:

    quarters are slightly thicker although size is nearly the same. roughing the edges of older pennies prevents them from being recognized as a penny as they do not drop through the ‘paths’ .
    these kind of older manchines or vending/meters use weight and size to dtermine the coin as appose to laser or precise weight now a days - so it is possible on older vending/meters if the coint is scratched quite significantly.
