Coin Numbers

Discrete Mathematics Level 4

You have 3 coins : a 9 cent coin, a 60 cent coin and an 80 cent coin. If are allowed to rotate and rearrange the coins then how much diverse 3-coin numbers shall you be able to make?

Clarification : 09 is the same as 9.

P.S. Harder version coming soon! :D
