Welcome to the CCF!
The newcomb book is a bit outdated and can be rather obtuse imo. Noyes book is much better.
Found this not sure if it will help or not.
Here are a few hints to help attribute early and middle date Large cents...
First, look at where certain diagnostics are on the obverse, Where is LIBERTY, in relation to a normal positioning?
Does the date look kind of odd (pointy, wide, doubled ones, certain digits too low, odd spacing of digits, date into bust of Liberty, etc)?
What is LIBERTY's position in relationship to correct curvature, near or far from the rim, recut letters, broken letters, etc?
Are there recut stars, die breaks,
Cuds, etc?
Look at Ms. Liberty's hair and Coronet, in relation to certain stars.
Then, look at the reverse. Do any letters look low, small, large?
Do any of the leaves have doubling?
Is there a center dot in ONE CENT?
Are there any die cracks or
Cuds?
How about counting the berries on each side?
Take a look at the positioning of the fraction, and look at the digits, to see if there is an error. There are more diagnostics to look for, but this is a start.
