Emily's $5.00 System: 
    A method for persons with a visual imprairment
    to more easily handle U.S. Currency
    ====================================================================

    1.  When you go to the bank, request that your cash be returned to
        you in ONLY $5.00 bills.  This way you only need 2 categories
        of currency in your wallet, billfold or purse.

    2.  The first category will be your Outgoing section.  So if you need
        $10.00 or $20.00 you just count out the appropriate number of
        $5.00 bills to pay with.

    3.  ALL CHANGE will come back to you in One Dollar bills.  So this is
        your second category which you can draw from as necessary, or else
        just deposit all the $1.00 bills back into your account at a later
        date.  

    4.  All confusion with whether a bill is a $10.00, or a $20.00 bill
        is thereby avoided since you never start with anything higher than
        a $5.00
