As of my last knowledge, Chase Bank does not offer exchange services for Iraqi dinar. Typically, major banks in the United States do not deal with exotic or less commonly traded currencies like the Iraqi dinar due to limited demand and potential risks associated with such currencies. You may need to find specialized currency exchange services or financial institutions that specifically handle Iraqi dinar for cashing in or exchanging. It's always a good idea to call ahead or check with the bank directly for the most up-to-date information on their currency exchange services.
