Solvent smears of some sort. Interesting affects, too.
This error occurs when a pressman is cleaning a printing plate or a roller and splashes excess solvent and it drips all over the place or he fails to clean up the mess before restarting the press. It can occur on any of the ink colors and on the front or the back of the exposed note.
You can search the Heritage Auctions (HA.com) sold items website for Currency ink smear errors and get an idea of what they have sold for. They show selling about 150 of these things over the years. No two are alike!
Neat error!
