The Treasury Department yesterday unveiled face lifts for Abraham Lincoln and Alexander Hamilton on the $5 and $10 bills, respectively, incorporating new security features in an effort to deter counterfeiters.

Similar to the redesign of the $20 note last year, the off-center portraits of Lincoln and Hamilton are larger than those on the current bills. There are other security features, as well, "to stay ahead of advances in reprographic technology," the Treasury Department said in a news release.

"The public is our first line of defense against counterfeiting," said Treasury Secretary Lawrence H. Summers. "If everyone checks the money that passes through their hands, it will put counterfeiters out of business. And that is the goal of redesigning our currency."

The new notes, pictured below, are scheduled to go into circulation toward the middle of 2000, gradually replacing the older $5 and $10 notes. Some of the new design features of the two notes are different. For example, a security thread is embedded to the left of the Lincoln portrait, while the thread is embedded to the right of the Hamilton portrait.

Microprinting: "The United States of America" is on the lower edge ornamentation of the oval framing the portrait.

Federal Reserve indicators: A new seal represents the entire Federal Reserve System.

Security thread: A vertically embedded thread to the left of the portrait indicates the $5 denomination.

Portrait: A larger, off-center portrait allows room for a watermark.

Serial numbers: An additional letter is added to the serial number.

Watermark: A watermark portrait is visible from both sides when held up to a light.
