Number 14 is just wrong. (“The only coin in U.S. currency inscribed with a numerical amount is the nickel, and it literally says the words “five cents.” How unhelpful is that to the illiterate or tourists? Or illiterate tourists!”) The US penny says “ONE CENT”; the dime says “ONE DIME”; the quarter says “QUARTER DOLLAR”; and each dollar coin says “ONE DOLLAR.” Could they be clearer? Yeah. Could they use numerals instead of just spelling it out? Sure. But it’s simply false to say that “The only coin in U.S. currency inscribed with a numerical amount is the nickel.” Did the author even bother to check, before publishing an obviously false assertion on the Intertubes?
