County Commemorative Pennies
Starting in 2006, the U.S. Mint will release five new pennies per year for the next 629 years. While the process will be a long one, residents of the nation's 3,143 counties and county equivalents have already begun debating how their regions should be depicted.
Does anyone else think this actually sounds like a pretty cool idea? First, the idea of a penny for your county is cool. Second, it would give notoriously short-sighted Americans some sense of perspective.
However, I would do it one penny per month, just like the quarters. So it would "only" take about 262 years to get all the pennies out.
