"Notes are the same size as each other in the good ol USofA aparrently, unlike here."
I can confirm this. All USA paper money is the same physical size, but with different designs. Even the legendary (but real) $2 bill. The coins, on the other hand, are different sizes, with larger coins being worth more. Except for dimes ($0.10), which are smaller than pennies ($0.01).
