A 19th century black felt, stovepipe hat famously worn by former U.S President Abraham Lincoln. After 200 years of neglect in the Museum of History, the hat has become worn and tattered and largely discolored with dirt and grime.
From the Museum of History Lower Halls, enter the Offices. Continue forward and head up the stairs. At the end of the stairway, turn right head down the hallway and enter the first room on the right. It will be filled with rubble; the hat is slightly to the left, by a large desk. The hat is lying at the floor about 2–3 meters from the room entrance on the left - quite easy to miss in the darkness, so put on your Pip-Boy light. If you can't find the room it is the northwestern room on the local map.
You can either fall down to the room from above when you go upstairs or get there directly from the offices.
- Lincoln's Profit Margins - can be sold to Leroy Walker, Hannibal Hamlin, or Abraham Washington. If the hat is sold to Hannibal, he says he will enshrine it, but since the hat is added to his inventory, his AI will make him wear it instead.
- Reverse-pickpocketing this onto a trader for added repair skill does not work. It appears that non-player characters are immune to the S.P.E.C.I.A.L. skill boosts that are provided by this item.
- If you do not already have 10 Intelligence, the Intelligence bonus gives +2 to the Science, Medicine, and Repair skills. This is the only headgear other than Button's wig that gives these bonuses.
