Identify

Since we moved into our current house, our tumble dryer has become very loud. I couldn't talk on the phone or even have a conversation with the family when it was on. So, today was the day for the arrival of a new one. When hubby was installing it, he found these coins in our vent. (No, that wasn't what was causing the noise.) I found it rather funny that there were multiple countries represented in the change in our dryer vent. Can you identify them all?
