The highest value note, the 5000K, due to condition is only worth about US$20-30 (catalog value). The rest drop in price from there. The notes are demonetized so they are no longer legal tender. Since many collectors thumb their nose at non-UNC notes, there is a smaller crowd that would love to have these notes in their collection. Still, you don't see these notes on a regular basis, and there are people that would like them including myself. They may have more sentimental value than monetary value to you, so you need to consider that. If you wanted to trade them, you would have them gone in an hour. If you want to maximize what you can get out of them, look to ebay. They are very nice notes despite their circulated condition.
