Thank you all very much for the feedback and informative pieces of information.
@bandsdean - I agree the obverse of the coin is a bit weakly struck, especially in the date region and below.
@Slider23 - OK. Are they caused by exposure to sulfur? I thought sulfur causes toning, not spotting. Any way to remove them. Would acetone do anything?
@BH - The thought that this coin was a forgery never even crossed my mind. I have yet to come across a true silver Chinese knockoff, let alone one brimming with luster and strong details. I'll get it sent in to PCGS/NGC one of these days but I have no doubt about the authenticity of this coin.
@Heymikep - thank you for that. I checked a few of Heritage
's listings with that die description and there are definitely similarities. I can't really tell the difference between the varieties but you may be correct.
@two_tonev35 - You're right about the wipe marks; I saw them immediately when I was looking over the images. I often expose my coins to a strong direct light when I take pictures and that usually brings out a lot of detail you can't see with the naked eye. I looked over that field in detail and no wipe marks can be seen with the naked eye under any lighting or at any angle.
As for grading, most of you said AU53-55. I don't know if I agree with that. I have looked at a lot of AUs on Heritage
and none look like this one. Most look like they've been wiped with brillo when you really start to enlarge images. Even the cleaner ones have a lot of flaws in the fields, and flat spots are readily seen, especially on the knee/thigh, hand holding the cap, breast, and bottom section of the rock liberty is sitting on, not to mention questionable luster. I linked a few below. I may be wrong or perhaps biased (or both) but I honestly think this should grade MS. https://coins.ha.com/itm/seated-hal...ption-071515https://coins.ha.com/itm/seated-hal...ption-071515https://coins.ha.com/itm/seated-hal...ption-071515https://coins.ha.com/itm/seated-hal...ption-071515https://coins.ha.com/itm/seated-hal...ption-071515
