Here are a few more I got. Just a bunch of overdates: 1897/6-B 1907/7-B (OK, technically a repunched date, rather than an overdate) 1908/3-B 1911/00-B 1929/1-B One more to post tonight.
Mintage numbers are available here. They don't necessarily reflect what was released or what survives. The 1921-B had its entire mintage melted, save for a few coins. 1934-B is also one of the scarcest dates, despite a mintage of over 17 million, most never being released. The most common dates seem to be 1929 and 1930. This is no doubt due to asymmetric attrition throughout the series. Pre-1921 dates were probably recalled to England and melted during WWI. The design also made them really popular for jewelry. Mintages of the overdates are always included in those of the intended date of the coin. One can assume that the mintages for these are the average number of coins struck on a die, unless there is a lot of damage to the die that would cause it to be retired before such a number was struck. It's very tempting to study these as I do Morgan Dollar VAMs, but the information and the coins are both far more difficult to acquire.
That first one is gorgeous! You're kinda making me want to pick one of these up. Do they come in prooflike?
Not aware of any PLs. Population reports don't list any. The 1900-B I have, which I posted on the other thread, is the closest to PL, but it's a long way off. You can sort of see what I mean on the reverse. I don't know a lot about die preparation for these. I don't even know if the pre-WWI dies were manufactured in London or Bombay, although I assume London. Final die preparation would have been at the Indian mints, and while they did strike these in proof, demonstrating that they were capable of mirrored finished, I don't know if they would have taken the same care to finish preparing a business strike die.
I didn't see any listed in the pops either, which is why I asked. You clearly have looked at more of these than I have. Cool coins, either way!
