Do you mean using the same coins for all amounts? If so then:
4 pennies
1 nickel
2 dimes
1 quarter
1 half-dollar
Answer: 9 coins.
However, all amounts from 1 cent to $1.00 can be made in some set of 8 or fewer coins. (But none of these sets can make ALL values.)
If you are asking for the fewest number of coins needed to be able to make any amount, and ONLY the amounts from 1 cent through $1.00 (i.e., they total $1.00) then:
5 pennies
2 nickels
1 dime
1 quarter
1 half-dollar
(which all add to $1.00)
10 coins
All of these answers increase by one if a half-dollar is disallowed as it is replaced by 2 quarters.

Of course, it depends entirely upon the currency of the country you are considering. The USA had both $1 and 50 cent coins, so either 1 or 2 would be the answer. Although the 50 cent coin may not be still in circulation, I'm sure it is still legal tender and anybody would be glad to get one as payment, since most are worth more than face value.

from 1 cent to one dollar the difference is 99 cents. so the fewest numbers of coins to form 99 cents would be 3 quarters, 2dimes and 4 pennies which equals to 9 coins

In order to have the coins you need to make change for every denomination, you need:
4 pennies
1 nickel
2 dimes
3 quarters
10 total coins
If you count half-dollars, the answer is slightly different:
4 pennies
1 nickel
2 dimes
1 quarter
1 half-dollar
9 total coins

If it is still being mae, a one dollar coin (1 coin), or if the still make a half dollar coin (2 coins). In today's case, 4 quarters (four coins)

I have never seen half-dollar coins, so I will stick to pennies, nickles, dimes and quarters.
4 pennies, 1 nickle, 2 dimes and 3 quarters should do the trick, that is, 10 coins in total.
