I gifted this subscription to my 10-year son and he absolutely loved it. The currency notes were mostly in circulation and new, with some historical and old currencies included. That led to the kid trying to understand and learn more about each country and the history of the currency. It was a brilliant purchase and I highly recommend it. The only negative comment is that the value of the currencies in most months did not exceed the value of the subscription unlike what is claimed in the promotional material.
