Question: “Is [A currency book] how banks in the United States are going to check for counterfeit bills? Or should we find a bank with some sort of machine?” Some will send them off to the mother bank if it’s a small bank. That’s why I encourage you to go to a big bank. Some of them might use just the currency book and that would probably be the smaller banks…You just don’t want to lose sight of your dinars wherever you go. If you give them, they better give you the equivalent in American money. Don’t let them take your dinars…
