Lifehacker reader and blogger BostonMark posts a handy tip on what change you should be carrying so that you can cover any change requirement from $0.01 to $0.99. The magic combo:

3 quarters

1 dime

2 nickels

4 pennies

Of course, 99 pennies would do the same thing, but this little combo gives you the most flexibility with the least amount of change (10 coins) in your pocket. And yes, once you make one purchase requiring change you may not be able to hit the exact change next time. But if you leave the house with these 10 coins every day, you can consider yourself well prepared in the change department, and as Mark points out, it's a great way to slowly get rid of your pile of change.
