Lincoln's Hat

Lincoln's Hat can be found in the Museum of American History.

Location
From the Museum of American History Lower Halls, enter the Offices. Once the player goes upstairs, turn right and enter the first room on the right. It should be the northwestern room. 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 PipBoy light.

You can either fall down to the room from above when you go upstairs or get there directly from the offices.

The intelligence bonus gives +2 to the Science, Medicine, and Repair skills (assuming you do not already have a 10 intelligence). This is the only headgear other than Button's Wig that gives bonuses to these skills.

The hat is part of the unmarked Lincoln's Profit Margins quest.
