This is odd.

I found the remains of my childhood "coin collection" buried deep in my closet.  I don't even know where I got half of them.  This is what I have:

Canadian - one "loony" and one "toony" (one-dollar and two-dollar coins, respectively), two 25-cent pieces, two 10-cent pieces, and four pennies.

British - two five-pence coins, two two-pence coins, six pennies.

German - two different two-pfennig coins, one from 1989 (reading "Deutsche Demokratische Republik") and one from 1992 (reading "Bundesrepublik Deutschland"), and one 2-pfennig coin.  I'd really like to find out the history behind the two types of coins.

Austrian - two one-Schilling coins and one ten-Groschen coin.  I'm not exactly sure how the math works in that currency.

Swiss - two 1/2-franc coins

I also somehow ended up with one Swedish ore and one Greek drachma; who knows where those came from.
