I think I've attributed all 4 coins, but looking for independent confirmation. Coin 1 (1834)... Coin 2 (1841)... Coin 3 (1847)... Coin 4 (1853)...
Looks like someone tried to hammer the Newcomb variety out of the 34, Can't quite tell if they succeeded or not though.
I have the Noyes set which includes the late dates. But my skills and knowledge really aren't very useful beyond 1807 over an average collector.
The 1834 is easy, there are only 7 varieties and you can pretty much ignore N-7 (proof only and only 8 known) There are 2 varieties with large stars and 4 with small stars. All of the small star varieties have star 6 pointing just about right at the point of the coronet. On this coin it is well right of the coronet point so it is a large star variety. (N-1 or N-2) On so look at A3 (last A in America). On N-1 the leaf point is below the right most serif of the A, on N-2 it is below the center of the A. This is N-1. As for the late date coins, they are usually very difficult to impossible to attribute from photos and in general I don't even try. If the date position isn't diagnostic the identifying features are usually too small/indistinct to see unless the images are large and very sharp, and preferably the coin is XF or better. Having said that the 1841 is either N-4 or N-5 and I am leaning toward N-4 because I think I can see the die crack running from the star point on star 8 to the rim over star 9.
