Problem of the Week (POW): Making Change

Please choose one of these to do, depending on your level of challenge:

* Find all the ways to make change for $0.25.
OR
* Find all the ways to make change for $0.50.
OR
* Find all the ways to make change for $1.00.

Devise a system so that you are confident you have found all the possible combinations of coins, and write out your thinking, so that others can follow your reasoning. More credit will be given for a thorough explanation than for a correct answer.
