The Canadian mint pulled a switch-er-roo on this one- as in this case it is the large bead that is worth much more.
Now I must put in a word here. Back in 1966 right after the Canadian dollars came out, I purchased two of them at our coin club auction. Nobody had discovered variety small or large bead differences as yet-on this Dollar. Well, Low and behold, I am the luck owner of the small bead 1966 Canadia Dollar.- I have never been that lucky before. That coin is resting in a safe place. Yes, I do like Canadian coins- Espeically those of the middle 1800's
