I had a great many coins to count and roll, and I needed to keep track of how much I was getting rolled up to be able to confirm with the bank when I took it all in, so I decided to write up a fancy program on my brand new CE to handle the task 
This counts both up and down, by pressing either the + or - key and pressing 1-4. This also counts up how much money you have rolled up in real time, and when you quit the program, it archives the list so it stays protected.
Just something fun and useful I thought I'd share with everyone. Here is a download link: http://www.cemetech.net/programs/index.php?mode=file&id=1278
If nothing else, you might find something useful in the code to use with your own project.
