It appears to be the Browning-4 (Rarity 1). The site I use for the attributions when I don't have my book readily available is here: https://www.ngccoin.com/coin-variet...raped-bust-and-capped-bust-quarters-vscid-10/ It doesn't have every single variety, but it has the vast majority of them. For rarity ratings, the following site is relatively okay: http://www.coinfacts.com/quarter_dollars/capped_bust_quarters/capped_bust_quarter_dollars.html Some of these have been updated since the site was made but it's still reasonably accurate. The site doesn't have the R.# ratings but Rarity 1 (R.1) = very common, R.2 = common, R.3 = scarce, R.4 = very scarce, R.5 = rare, R.6= very rare, and R.7 = extremely rare. If you're particularly interested in the bust quarter series, I highly recommend Early United States Quarters 1796-1838 by Steve Tompkins.
I think from what have put together from these sites it's b-5. Could be b-3. But from the 25 C on rev I'm pretty shure it's b-5. Your link calls this rare
It's B-4, on B-3 the olive stem extends to the serif of the C while on the B-5 it extends well past the C.
The 34s are easy to tell the variety. The B-1 had a reverse change with a totally different looking eagle (unique hub used only for the 1833 B-2 and 1834 B-1) and a 2 lines per stripe shield. The B-2 and B-5 used the proof reverse which also has a very distinct looking eagle (unique hub used only for the 1834 B-2, 1834 B-5, and 1835 B-2), and they are both very scarce. This coin has the regular eagle, however, meaning it could only possibly be a B-3 or B-4. On B-3 the spacing between 25 and C is close, and on B-4 the spacing is wide, so this is a B-4. It's an R1. The small capped bust quarters only have 36 varieties, so it doesn't take long to memorize them. You just need to realize that variety identification doesn't require an analysis of the entire coin. You can boil it down to one or two simple features per variety. For example, the 1836 B-3 is the most common of the 5 1836 varieties, and it's the only one where the eagle has a tongue, so when encountering an 1836, the first thing you look for is a tongue on the eagle and you go from there. For 1834s you check the type of the reverse, since that narrows it down to 1-2 varieties immediately, etc.
So the die gouges through liberties neck and ear as seen on 3 & 5 mean nothing? Because they do not show on any of the others. Sorry double post. Just trying to learn more about this.
If you're talking about obverse die cracks, there aren't any that are significant for 1834s except for the B-1 post remarriage. The B-3 and B-5 used different obverse and reverse dies, so they aren't going to share any die cracks (or anything else). The only time the obverse is diagnostically relevant for an 1834 is when you need to distinguish between the B-2 and the B-5, since they both share the same proof reverse die. There were 3 different eagle designs used throughout the series. Here are some photos of coins in my collection that illustrate the eagle types: This is the typical eagle you will see on almost every variety (this one is from a large letters reverse). Small variations exist such as whether or not the eagle has a tongue, the size and shape of the arrowheads, and for one variety, the existence of berries on the olive branch, but they all basically look like this: This is the O/F reverse used briefly when the reverse was changed to reduce the number of lines in the shield stripes from 3 to 2, although this was quickly reverted. This reverse was only used on some 1833 and 1834 dated coins. You'll note that aside from the difference in the number of lines in the shield stripes, the general shape and angle of the eagle's wings, neck, and head are completely different than the above example: And this is the proof reverse. It looks more like the typical reverse than the O/F reverse, but it's different than both of them. The wing on the left has the shape of the left wing on the typical reverse, but the right wing has a shape more like the O/F reverse. The eagle's brow is flatter and more defined, it has a tongue, and the feather pattern is quite different from the other two eagles. The 1834 B-2 and B-5 both use this proof reverse die:
Not die cracks four die gouges through neck and ear. Look in this area on my coin a bit worn but they are there will take better pics after work today.
OH those are not die gouges, those are shield bar clash marks by the ear. That's present on a lot of the varieties in many years in this series, though the angle of the clash differs slightly between dies depending on the die rotation when the clash happened. 3 obverse dies were used between the 5 1834 varieties, and all 3 dies had clashing of the shield bars at the ear at some point in the life of the dies. It's not diagnostically relevant for determining the variety at all, however, it can be used to determine the die stage.
