Euro's, Pound's, and Rubbles

I just want to thank all those people who leave money in their clothes when donating to Goodwill; especially foreign coin. Needless to say Goodwill is letting me purchase the coins at discount... mostly because it costs a fortune to ship it and then the people who usually exchange the coin for Goodwill take a good percentage. Any how, I have about $50 US in foreign coin that we hope we can use in London airport as well as in Russia. Although, if you have foreign coin you don't know what to do with... please donate it to Goodwill, at least they have learned how to handle foreign coin.
