 The site I got these images from, НОВОСТИ В ФОТОГРАФИЯХ, is in a language I can't even identify much less read, so I have no idea what the post's commentary about them was. They are a series of closeup details of an American $100 bill and appear to be focusing on the engraving details that make them difficult to counterfeit. 

The details are striking. You can see more after the jump.
