Regular Expression (Regex) Validator to allow only positive whole value with or without commas

I've been working on a project with lots of previous developer validation issues and am trying to clean up some issues and add validation in spots.

I generally use this simple regex that allows only positive whole values and can accept commas if they are entered: 

"^([0-9]*,?)*$"

But in this case my program won't run if 0 is the value entered, so I need 1 to be the minimum value allowed. All else is the same. No decimals or any of that stuff.

I'm assuming I just need to add "not 0" to my regex, but not sure how to do that.

Allowed:

3,200
650
5
134560
100,000

Not Allowed:

0
3.2
-3.2

Thanks for your help!

Simply use this:

^[1-9]([0-9]*,?)*$

The first character cannot be a 0 and since it isn't optional either...
