5. Red Seal and Secretary's Signature: On the left side, you should find the red Federal Reserve seal, and the Secretary of the Treasury's signature should be present.
6. Microprinting: Tiny print along the top of the bill should read "THE UNITED STATES OF AMERICA." Another microprinting "TEN DOLLARS" should be visible near Alexander Hamilton's coat on the front.
7. Security Thread: Hold the bill up to the light to check for a security thread. It should appear as a vertical strip with the words "TEN" and "USA."
