If you look close at the center point of the normal 63-3 it's blunt but on the highest relief of it there's more of a point.
That shows very well in the CPG picture.
On the doubled one because it's weak and a tilted hub class 8 double die it only shows a partial design and only the highest relief part of the second 3 is there so it looks pointed. _________________ Ed
Some books say it's a high 3 over a polished off low 3 but I think they mean it's a class 8/tilted hub but at some point they polished most of the low 3 away and that's why the early state shows the lower tail and the later state doesn't. _________________ Ed
