Exclamation Using grep and expressions

How can I use grep expressions so that i can find strings like the ones bellow:

New York, NY
Virginia, VA
Oregon, OR

As you can see each city starts with capital letter then it follows up with a comma, and then with the Abbreviation of the city.

I used :

grep -w '[A-Z].*[a-z][,][' '][A-Z][A-Z]' filename
But i get no results.. pls help meeee

grep -w '[A-Z][a-zA-Z]*[,][ ]*[A-Z][A-Z]' <FILENAME> works for me.

I'm no regex expert so it could probably be refined a bit.

If you want to match one uppercase letter, and the rest of the city name must be lowercase:
grep -w '[A-Z].[a-z]*[,][ ]*[A-Z][A-Z]' <FILENAME> seems to work
