I recently picked up this massive Mongolian horseblanket for just $9, UNC. These are not worth much more than that, despite their high grade and gigantic size. I've looked all over and have never seen a 100 Togrik in circulated condition, leading me to believe this was some sort of commemorative issue, remainder, or otherwise NIFC. Obverse features Damdin Sukhbaatar, also knows as the Father of the Mongolian Revolution. Reverse is a fancy design very reminiscent of some older Russian designs. Here's a size comparison between this and small size USD. Not the largest note I have by far, but certainly the most recent large note I have. You don't really see big banknotes in the latter half of the 20th century at all.
It's reminiscent of Russian notes because it was printed by Goznak in Moscow. Usually notes in the socialist countries tended to be smaller by then, so that note is particularly unusual.
