Question: "My denominations are all in 25k notes, would I be able to exchange those?"
Yes you can exchange 25k notes. You can exchange all of the notes.
The only one you can't exchange is the one that has the picture of Saddam on it. Those are called Swiss notes. You don't want those. The other one too is the 50 Iraqi dinar. Those are null and void. They're gone. You can't use those.
