Day-Lewis, who stars as former US President Abraham Lincoln in Spielberg's Oscar-nominated film, has been a major supporter of Ireland's Wicklow Hospice Foundation since his mother lived out her final days under their care in 2009.
And to give the group a boost, the filmmaker has handed over a set of gloves and miniature soldiers featured in the picture, as well as Lincoln's handmade knife, for the organisation's upcoming charity auction.
The items will go under the hammer at the movie's European premiere in Dublin next week, and chairman Brendan Cuddihy is overwhelmed by Spielberg's generosity.
He said: "Props of this quality never come on the market and are closely protected by movie studios. Now that Lincoln is hotly tipped to scoop multi-Academy awards, we're being told the value is even higher."
Lincoln currently leads the 2013 Oscars race with a whopping 12 nominations.
