Performed a search, but surprisingly came up empty-handed.

No, they can't be openly sold, but I'm generally curious as to the range of perceived cash value of a PlusPoint. Of course, they're worth nothing the day after they expire, but in their prime of life, what's the value you'd put onto a PlusPoint? What's the best usage? What's the poorest usage? What's the highest possible cash value you see a PlusPoint as having?

Thoughts?


Mod: If search was somehow broken, feel free to merge this as appropriate.
