In a certain country, it takes a minimum of exactly 5 coins to make 13 cents, and a minimum of exactly 4 coins to make 14 cents.

What are the denominations of the coins (of value less than 15 cents) in this country?

Bonus: What country is it?

(In reply to One Possibility by Charlie)

There are any number of sets of coins that can be made with fractional parts, for instance ¼¢, 12¢, and 13¼¢.

There is, however, one solution with all coins in integer denominations.
