I have a question for Americans about money?

Not to sound ignorant or stupid (at least no more stupid than the people who ask me if I speak Canadian, or the people who ask what it’s like to live in an igloo), but I was just wondering, in the US do you have:
pennies ({content}.01 coins)?
nickles ({content}.05 coins)?
dimes ({content}.10 coins)?
quarters ({content}.25 coins)?
Loonies ( coins)?
Toonies ( coins)?
And if not, what do you call them?
So do I, but those aren’t common here
