Okay. My question: I see is a mintmark that leans to the left and has the bottom half filled, an missing serif on the R in DOLLAR, and the arrow rods lose their thickness towards the arrowheads. I cannot find any literature about a variety with these diagnostics, though I found something similar: 6. Large S. Blunt tail to R of DOLLAR: Breen-5811. Upturned serif broken off. At least two positional varieties: (a) mintmark leans crazily to left; (b) S upright; normal periods. Both are presently considered to be rare. http://www.pcgs.com/books/silver-dollars/Chapter12Listings-045.aspx Is this a rare variety?
Breen-5811, the "Broken Arrows" type. Look here: https://coins.ha.com/itm/trade-doll...0-1141.s?ic4=ListView-ShortDescription-071515 https://coins.ha.com/itm/trade-doll...357.s?ic4=GalleryView-ShortDescription-071515 Between the nice unmolested look and the difficulty in first, finding one to counterfeit and second, counterfeiting the arrow shafts, I'm thinking yours is pretty likely authentic.
I was going to mention the Gobrecht Journal but forgot the author who wrote the article. The coin is OK, and at present your coin is classified as 2m/2m. Stay tuned as this will be changed soon.
One interesting thing about the 77s broken arrows is that they attempted to fix the die by re-hubbing and created the 78s DDR with fixed arrows but misaligned details
My broken arrow, it looks unc (but ugly) to these eyes but what do I know. It has that deep dish flash under the splotchy toning
