If you're thinking of buying or selling currency it can be useful to know how good today's exchange rates are compared to the past. There are many sources of exchange rate data on the Internet but they almost exclusively show 'interbank' exchange rates which are used by banks and currency traders to move large volumes of currency and are not available to most customers. Whilst these rates can give you an idea of how the rates have changed over time, they are not a useful comparison of today's rates because they are always better than the rates available on the high street.
Our historical currency graphs are different because they are based on real data - we show you the actual rates that currency could be bought at in the high street on any given day so you can see exactly how today's rates compare to the past without any calculations or guess work.
