Just FYI you can look up stuff like this at no cost. It’s not even close to being true. A Canadian polymer banknote costs about 20 cents to manufacture and the smallest denomination is $5. Coins cost a few cents to make (even $2 ones). It’s just the penny that lost so much of its value over time that it costs more to make than its worth.
And? That’s true of most coins. It’s probably true of the bills as well.
