Treasury and the Federal Reserve had touted the new bills' sophisticated security features that were 10 years in the making, including a 3-D security strip and a color-shifting image of a bell, designed to foil counterfeiters. But it turns out the bills are so high-tech that the presses can't handle the printing job.
1 billion unusable bills have been printed. Some of the bills creased during production, creating a blank space on the paper, one official told CNBC. Because correctly printed bills are mixed in with the flawed ones, even the ones printed to the correct design specs can't be used until they 're sorted. It would take an estimated 20 to 30 years to weed out the defective bills by hand, but a mechanized system is expected to get the job done in about a year.
flawed bills, which cost around $120 million to print, will have to burned.
