Here is the RegExp that should work:

^[1-9]\d{0,2}(?:\d+|(?:,\d{3})*)(?:\.\d{2})?$

Here you can test it against various strings.

This one should do it:

value.match(/^[0-9,.]+$/);

Believe it or not, this behemoth seems to work, and it permits the dollar sign.

^\$?([1-9]{1}[0-9]{0,2}(\,[0-9]{3})*(\.[0-9]{0,2})?|[1-9]{1}[0-9]{0,}(\.[0-9]{0,2})?|0(\.[0-9]{0,2})?|(\.[0-9]{1,2})?)$

I borrowed it from RegExLib.com. If this regex doesn’t work for you, perhaps one of the others will.
