Logic Level 2

I have $n$ coins one of which is lighter than all the other $(n-1)$ coins. The other $(n-1)$ coins are all of exactly the same mass.

I have to use a weighing balance to find out the light coin.

I am sure that I will only need at most 3 weighings to determine the lighter coin. What is the maximum possible value of $n$?
