"What Mr. Dennis may have thought was a nickel and dime theft was, in the end, the equivalent of a major bank heist," FBI Special Agent Roger Stanton said in a news release Monday. "Now, he will be a convicted felon who must repay all the stolen money."

Dennis, 49, is charged with bank theft for stealing the coins from Federal Reserve Bank of Atlanta while working for Brink's in Birmingham, Alabama.

Dennis used his access to the the Federal Reserve Coin Inventory to access ballistic bags that each stored $50,000 worth of quarters. The bags are stored on skids.

CNN reported that the thefts occurred between Jan. 1, 2014, and Feb. 20, 2014.

Dennis used Sunday, Feb. 16, 2014, a day off from work, to steal 784,000 quarters.

Dennis faces a maximum of 10 years in prison and a $250,000 fine.
