What is Java Regex to match number then space then 3 alphabet char?

I want to validate the about of money with the currency Unit. 

100 USD : valid
1.11 USD : not valid
1,12 USD : not valid
12 US : not valid

So the valid string is "the number then space then 3 alphabet char".

text.matches("^\\d+ [a-zA-Z]{3}*$")

I got error: Exception caught: Dangling meta character '*' near index 16 ^\d+ [a-zA-Z]{3}*$

So how to fix it?
