When you get to
www.oanda.com go to Currency Tools on the left-hand side and click on "FXHistory".
This brings you a page with a bunch of menus. You can select the "from" and "to" currency, the date or dates you want information on, and the type of rate you want (click on the drop-down menu defaulted at "interbank rate" and you'll see whole list, including "interbank rate: +3%"). (The "interbank rate" is sometimes called the "base" rate. It's the amount one bank charges another for transactions of -- I think -- $1 million or more, before adding any conversion fees or charges.)
Fill in the blanks and click on "get table" and you'll get a table including the average, high, and low.
For example, for conversion of US dollars (USD) to Polish new Zlotys (PLN) on 04/18/2009 to 04/18/2009 (i.e., that date only) at the interbank rate, you get:
Conversion Table: USD to PLN (Interbank rate)
Time period: 04/18/09 to 04/18/09.
Daily averages: 04/18/2009 3.29170
Average (1 days): 3.29170
High: 3.31200
Low: 3.23850
