Correct change

If you always want to go to the store with the correct change from 1 to 99 cents, but want to carry the fewest coins possible, what is the number and type of coins needed?
(using only US pennies, nickels, dimes, quarters)
I figure some people already figured this out long ago. Heck, this may become archaic info not so long from now in electronic currency.

There's no secret. Just know what you're talking about before you open your mouth.

I thought I had this figured out up to 50 cents then I looked up the answer and found out I was already wrong so I gave up... haha...
4 pennies, 2 nickels, 1 dime, 3 quarters

^ I agree
although your 7th coin can be 5 or 10c.
1 1 1 1 5 10 X 25 25 25 where X can be 5 or 10 - the first 7 coins get you 1 to 24 and the quarters cover the other parts to 99c (technically X=10 allows you to continue up to $1.04 so might be considered a superior answer). Also do they still do 50c coins like you used to see in Vegas, if so replace the 25 25 with a 50?
