This is almost perfect but if I type only a '$' sign it'll produce a match. I would expect it to require at least 1 digit.

When I use this in a .net regular expression validator it requires the commas in amounts > 999
Do you have any idea why?

A quality reg ex - thanks.
And by the way - ignore those idiots who have chosen to be ungrateful - anyone that can't validate for blanks etc. shouldn't be using regular expressions.

I think it's wonderful that it accepts blanks... One should attach a reqval to catch any empty fields before attempting to validate entries anyways.
What happens when fields are optional? If you require a value then you're in trouble... However if you allow blanks to pass then you're ok. If the field is indeed required, just add a reqval on top of it to avoid blank entries.
Wonderful regex! Thanks Tom!

Response to Mr. Clancy,
Is your question merely theoretical, about why/how this regex allows null entries to validate?
Are you needing a regex that won't allow null or $ only entries to pass?

<em>I confirm that the field is populated - hence it is fine with me if it matches blanks.</em>
But why should the regex allow an empty string to pass as a valid currency amount when it's not?

Thanks. It works fine now. I tweaked it just a little to allow a minus sign without a dollar sign in the data:
^(\$|\-\$|\$\-|-)?([0-9]{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 did a quick test on this by inserting vertical pipe operator (logical OR) within parenthesis, with along with the optional starting dollar sign. Hence:
^(\$|\-\$|\$\-)?([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})?)$

How can I change this validation expression to allow an optional minus sign before or after the dollar sign, and irrespective of whether a dollar sign exists in the data ?

Depending upon your application/use, these are both valid points.
For me, before I ever authenticate, I confirm that the field is populated - hence it is fine with me if it matches blanks.
As for the $ by itself, the data is stored in a numeric field in a database, so I'm stripping out the $ and , before passing the data through - I just want the flexibility for my users... And since the field is not required, this works.

Should "$" (by itself) be a match/valid?
