perplexus.info :: Weights and Scales : Yet one more coin sorting problem

Yet one more coin sorting problem (Posted on 2004-05-31)

You have five coins, apparently alike, but actually of different weights. You also have a two arm scale.

Can you manage to sort the coins in ascending order, using the scale only seven times?

Bonus question: can it be done in fewer weighings?
