This is some information I received on the money situation in Iraq from
my Russian friend living there.
...unfortunately in Iraq there are no ATM or banks where you could cash TC. SO you better to have a cash with you. They prefer 100 USD bills. For example if you change 100 bill the rate will be 1650. If you change 20 bills the rate will be 1600. If you change 1 bills the rate will be 1550.
P.S. Despite all of this Iraq is a cheap country. Expect to spend here
