1965,1966 Canadian One Dollars: Which Type? Help!

Hello all!
First time poster here, go easy on me.
Anyway I would love if someone could help me and verify which variety these coins are. The more I look at them the more they change.

First one is a 1965, the "5" is pointed but I can't decide if the beads are sm., med., or lrg.?
Second and Third are 1966's and the beads, sm. or lrg.?





1966's. The first,





Then the 2nd,





Any advice on taking photos would be great too, it took me about 6 hours to get these some what visually pleasing.

Thanks!
