hmmm, i know whatt you mean. I came back to canada with 50,000 pesos from the philippines and cant get rid of them, they will not take them. The only solution i found was to go to the airport where they accept and exchange currency (any airport), i didnt loose much but i was surprised to see that filippino pesos are worthless in another country! I only use my debit card or credit when i travel and only change money when i have to!
