1834 Coronet Large Cent - Which Variety?

There are only 7 varieties for this year and only two of them have the small 8, N-1 and N-2. Your coin is a N-2 and appears to be an early die stage. N-2 always comes with die cracks on both obv and rev but I do not see all of them on your coin, just the crack between stars 12 and 13. I don't know if it is because of the photos, the lower grade of the coin or the stage of the dies. This obv was first used on N-1 were it cracked, so all the N-2's should be cracked. The crack between 12 and 13 came late on N-1 so the other cracks should be there as well.

If you are speaking of an online reference for middle dates the only one I know of is Newcombs book from 194.

For images of all the middle date vareties there is the Dan Holmes collection sold by the goldbergs

With practice you can just use the images for variety identification.

For a physical library the Breen book is good for the early dates. For the Middle dates the book you want is The Cent Book by John Wright. If you can find printed copies of the two Dan Holmes sales I linked earlier I would HIGHLY recommend them. (I don't know if the Goldbergs still have copies, but they should be available through numismatic literature dealers.

For the late dates the book you want is Attribution Guide to United States Large Cents 1840 to 1857 by J R Grellman. There is a Dan Holmes catalog for these as well but they usually are not attributable from the pictures. The identifying features are too small/faint to show up in the images.

The middle and late date books are hard to come by second hand and are easier to get straight from the authors (I have their addresses if you want them.) The Breen book does show up second hand and is currently out of print so it will become harder to obtain with time.
