The three currency rules describe a quantity of currency up to one million dollars and 99 cents.
Two of the currency rules limit the maximum quantity that can be recognized. The names of these two rules indicate the limit. For example, Currency_US_upto1000 accepts whole quantities up to and including $1000.00.
