This type of forgery is a federal crime and is punishable by up to 10 years in prison, a fine of up to $250,000, or both. There are two types of Forging Endorsement on a Treasury Check, Bond, or Security of the United States: 1. Forging Endorsement: This type of forgery involves signing someone else’s name on the back of the Treasury check, bond, or security. 2.
