I'm honestly not 100% what the market value is for the lower denominated tokens. As I mentioned earlier, I'm open to any offers or suggestions for that matter! lol
I would recommend doing an auction to determine the market value. Start it at 0 or face value and see where it goes from there.A friend told me 0.7 wouldn't be far fetched, but it does seem high from what I've seen. The markup was more off of the tokens current condition. I would be comfortable letting it go for 0.5BTC range
