These poker chips are authentic props from Cowboys and Aliens, used in a scene where the characters are forced to spend a night on a destroyed riverboat casino that has been overturned. In this harrowing scene, the group is unexpectedly attacked by the invading aliens, and scattered chips can be seen amidst the debris of the ship. These screen-used chips serve as a memorable and tangible piece of the film's unique blend of Western and sci-fi genres, adding to the immersive experience of the movie.
