answer:I’m not American, but I agree that the US should use $1 and $2 in coin from only – it seems illogical to use notes for such small denominations. I’ve heard too that the US is one of the only developed countries to have notes for a low denomination such as $1 and $2. Not only that, but I think they should switch to polymer (plastic) bank notes, as they are so much better – you can’t accidentally tear them, they aren’t flimsy like paper, they last longer, they’re waterproof (and can survive the washing machine) and are harder to counterfeit (with that little window in the corner!). And colour-coding the money wouldn’t be a bad idea either – at the moment you have to actually read the notes to see what amount it is… compare to Australian money, where each note is of a different colour and size.
