$100 Bills to Be Destroyed After Printing Mistake at Factory

A small printing error is presumably proving very costly for the U.S. government after a currency factory ruined 30 million of the next generation of $100 bills.

Originally slated to go into circulation in 2011, the new bills have experienced a variety of setbacks, the latest of which involves a printing mistake known as "mashing," which is caused by applying too much ink to the paper.

The error has forced the Federal Reserve to return tens of millions of notes back to the Washington, D.C., facility and demand its money back. The returned notes will be destroyed.
