What's The Most Expen$ive Canadian Coin In Your Collection?

The most expensive coin I own is between myself and the person who sold it to me. I've
never mentioned it to anyone, even on coin forums. That's not going to change ;o)

This 1910 is one of my favorites. I found out a while after buying it that it came from the Canadiana collection, and that I gave up too much for it (in hindsight). It's still less "valuable" than my 1913 broad
leaves that I use for my avatar, but value isn't everything.
