I will be traveling soon and I have a bag of about $ 30.00 in various Canadian coins. Sorry none are Silver .These belong to my daughter that she found from a Grandmothers stash. Would it be best to exchange them for currency at a Canadian bank ( I do not have an account and don't want to pay a bank fee ) Or should I give them to the Casino Cage for Currency, since I think all slot machines will be the type for paper tickets. I will be staying in Niagara Falls and walk across the Border. Thanks
