MORRISTOWN, N.J. (Reuters) - A teenager who admitted printing counterfeit $20 bills off his home computer and giving them to his friends was sentenced Thursday in a New Jersey court to a year's probation.

The 18-year-old, whose name was not revealed, pleaded guilty to conspiracy and theft by deception in Family Court in Morristown, New Jersey.

He said he digitally scanned and printed currency, using his home computer, and gave between $1,000 and $1,500 worth of the fake bills to several friends.

Using the fake money to buy gum, potato chips and soda, the friends would kick back $10 for every $20 and keep the change, he said.

"I honestly don't know what went into me," he told Judge Salem Ahto. "I never did anything bad before. I know it was a horrible, horrible, horrible mistake that I made."

His identity was kept confidential because he was a minor at the time of the crime.

The judge also ordered him to tour the county jail.

Another teen who participated in the scheme pleaded guilty to the same charges and received the same sentence, and four others were slated to appear before the same judge on similar charges.

Federal counterfeiting charges were not filed against the youths because they all were too young, authorities said.
