It is a long play but if you did buy British Pounds around 2001 the pound was worth about $1.50 US. The rate today is over $2.00. Some British Banks will only offer depositors .25% interest or less on amounts less than $50,000 US. Fees will take that pittance. No interest return but better exchange rate.
BP to US$ could reverse as well.

If you did have a lot of cash to deposit/transfer overseas, the federal government would probably put you on the Homeland Security watch and the airports would make you dance like a monkey.
