Wayne Victor Dennis, who was convicted of printing $15 million in fake $20 bills that were so convincing authorities said the currency spent years in circulation after he went to prison, told KYW-AM the new $100 bills contain many security features, but the most intimidating feature is a 3-D ribbon made of thousands of tiny lenses.
Images of bells on the ribbon turn into 100s when the bill is tilted.
"It's a great idea and I think it would be the most difficult part to counterfeit on this new bill," Dennis said.
"I would never -- but if I chose to go back into that profession, I would never even waste my time on this currency," Dennis said. "If I was to go back into that business, I wouldn't even attempt it because there's just too much sophistication."
