1966 Canadian Silver Dollar - Small Beads ?

That looks like the large beads type Gjs1985
The small beads variety has beads so small that you could fit an extra bead in between the spaces.

Just read the previous posts in this thread.
There is plenty of info including a web site.

Hi everyone, new member, but I'll be back as we inherited lots of coins from my dad who was a professional auctioneer.
I came here looking for definitive answers on the small versus large beads, as we have a bag of them. I ended up taking some photos and discovered they seem to be the large bead version, despite a collector glancing at it and immediately stating they were small.
I enlarged some photos and marked them to highlight the difference, and the large bead version has the letter clocked so that the "I" is centered on the bottom edge of the bead, while the small bead version is centered slightly below the center of the bead. I like canuck888's method though, and the dots between the letters are 22 pixels in my larged photos, and the beads are 24 pixels. Below is a composite reference shot.

That's the best comparison shot of small/large beads that I have seen! Great reference shot.
