• Currency: [0-9]{1,3}?,?[0-9]{1,3}\.[0-9]{2}

  This pattern will look for 1 to 3 digits, [0-9]{1,3}, followed by a , and then, by 1 to 3 digits followed by a "." that is followed by 2 digits. The ? means a 0 or 1 instance of the pattern, so in this case, anything followed with the ? is optional. Examples of this pattern are 20.00, 50000.00, and 600,000.00.
