And the 3rd marker is whether the tip of the crown impinges on the bead at the top. If the bead is a full circle and not "cut" by the crown tip, it's a #1. If the tip makes the bead even slightly less than a perfect circle, it's a #2. The 4th marker is where the neck truncation comes to a point. On a #1, the neck truncation will end/almost touch the bead directly above the C in Canada. On a #2 (like these pics) the truncation will end just to the left of that ... between the two beads. If you look at them side by side, there is a big difference and that's the marker easiest to see from crappy
ebay photos. A #1 also "usually" has a D/C at about 6:00 on both the Obv and Reverse.
