Question

Which countries are still not independent?

Answer 1

Hong Kong still uses the Honk Kong dollar, and it appears that Macao still uses the pataca. Some non-independent places don't use the currency of the nation to which they 'belong'. The British Virgin Islands uses the US dollar, and the currency of Bermuda is pegged to the US dollar. The question of whether the Channel Islands are independent or not is an interesting one, but they do issue their own coins, as does the Isle of Man, but these are equivalent to the UK coinage. There's rather more issuing of stamps by non-independent places than issuing of currency.
