I'll say VF20. I'm far from an expert and probably wouldn't buy this raw unless I really trusted the seller, but I'll stick my neck out and vote that it's genuine at least.
Just like @longshot has stated.This one is much better then the other 2 you showed.I believe it's authentic but not being certified is a clue,steer clear unless you really know the series by heart.
I'd give about F15. I think it's probably genuine but couldn't be sure without larger pics. Generally, you don't see counterfeits of well worn common dates, but with seated dollars you never know! Retail for an unmessed with genuine one is around 300 to 350, per Numismedia.
This one looks OK to me. Probably cleaned, but it's an old cleaning, and the coin has retoned. It might not straight-grade at a TPG, but I think it looks acceptable.
The sharpness grade is VF - 30. The grading on the Seated Dollars is a bit different from the other denominations of this type because the “LIBERTY” is more prone to wear. It’s like the Twenty Cent Piece in that respect, although you should get more letters of the “LIBERTY” on the dollar than the double dime for the VF grade. Many of these coins have been cleaned, and you have be careful with counterfeits, but I think this one is real.
I made some comments and sited a link on my response to the 1859 LS dollar regarding determining authenticity. For this 1871: I'd grade this coin at VF-20 to 25. The obverse is better but the reverse is not better than 20. Better photos would help. Authenticity: I cannot make out what's needed to attribute the obverse and reverse dies. Based on the date/shield alignment, the obverse could be either 5, 8, 9, 10, 12. (I downloaded the obverse and show the alignment markers.) Reverse attribution depends almost entirely on die lines which are impossible to detect in these photos. Photos are just too unfocused and obscured by the flip. Without better photos I wouldn't even consider this coin. That said, I don't see anything about this coin that screams "FAKE!". Finally, why doesn't the owner crimp those staples?
Thank you guys on your opinions I appreciate it was worth a shot on one of them being real without the cost of money
