Collected coins from ship mates to change into dollars for a donation. Have anywhere from 3-6 pounds of coins from each country. Need a US company/ financial institution that will exchange the coins for dollars. Thanks.
If you have access to an airport where Virgin Atlantic flies, see if they will accept it. They have "Change for Children" appeal where they will accept pocket change in any currency on flights. I would try to call and speak to a manager first.
