Comparing string and integer in IF

hi,
I need to create an IF condition. I read a line from a file and get the 5 word using space as a delimited. This word can have only two values either '*' or '1-5'

I need to write an IF condition for two cases. I can either compare it to * or 1-5(or even 1 by cutting and getting only the first character).
But when I write it

eg, if [$var -eq '*' ]

If the value is 1-5 it says integer argument expected. If I write

if [ $var == 1 ]

In this case when the value is '*' it says string expected. How can I resolve this. Cannt I declare that the $var is always goiing to be a char. So I can use -eq '*' and -eq '1-5'.
