American Coins?????

I noticed that a lot of the activities with counting coins use American coins. I am aware that a lot of people use this currency, but I was wondering if they could add an option to change the coins to the ones another country uses, such as Canadian coins or British pounds. I have had difficulty with the questions including American currency, not because I don't know how to do the question, but because I cant understand how much the coins are worth. Since i'm Canadian, I don't know how to count coins without having a loonie or toonie (1 and 2 dollar coins) I hope that they'll change this soon!

A few things they could do:

1.  Make you add your nationality when you sign up, so that you get currency from your country, and you get questions written in your language.
2. Make doing questions with coins optional or not needed to master all skills, like an add on
