Canadian commemorative 25 cents for commemo from your country

I have quite a number of Canadian commemorative quarters and would like to swap them for commemorative coin from other countries (sorry, no 2 euro and no US quarters or dollars - I've got all that I need).
Looking for coins in XF or better condition only.
Due to the high cost of the postal services in Canada - non-registered mail only, unless you want to make a really big swap that can justify a $30 mailing fee.
