- To combine two ideas mentioned in this thread, I would believe that, *if* the
- energy states are equal, then (under a reasonable set of assumptions -- "soft
- landing" is *not* a reasonable assumption), the probability of a particular
- side is proportional to the surface area.

- I doubt very much that you can create a coin which lands on either side or
- the edge with equal probability regardless of the height it is "dropped"
- from, or of its angular momentum.
