After putting all those currency notes under the table glass top, I had thought of sitting down and trying to learn all the modern currencies of the world. This has turned out to be much easier than remembering capital names and much much easier than flags (which I am still working on at a slow pace).

See how many of these you can answer. Since the definition of “country” can be a bit subjective, the scope of these questions are the 195 countries in the UN (193 members, 2 observers).

1. What is the currency used by the most number of countries? (US and Canada both use dollars – but they are different currencies with different paper bills – US Dollars and Canadian dollars)

2. If you found the above easy – try this: which is the second one?

3. A surprising number of countries have “dollars” in their currency names (e.g. Canadian dollars). Can you take a rough guess how many of them have it?

4. What would be your guess as the next common word in currency name? How many countries would you guess? I am talking of same currency name but differentiated by its region or country name. e.g. “rupee” is used by both Pakistan (Pakistani rupee) and India (Indian rupee)

5. Speaking of the rupee, and this surprised me – how many countries have the word “rupee” (or its close derivative) in its name?

6. There are many countries which have its own currency – but also use US Dollars (e.g. the Bahamas). But there are other countries than the US that use US Dollars as the only currency. Take a guess how many and who are they?

7. What would be your guess as the shortest currency name (without attaching the country name in it)? How many letters? How many of them would you guess are there?

8. This might be a hint to the previous question. How many countries have currencies that are only 4 letters?
