Welcome to CoinTalk, tc.
If I were you I would not pay for this coin. I have VERY little faith that it is genuine. It would be better to take a negative for non-payment than to pay over $1000 for a coin that is very likely counterfeit.
From those photos it is hard to make a definite determination but it has the following going against it:
- The seller is in China.
- It is a raw 18th Century Silver Dollar. This type is HEAVILY counterfeited . . . in China (where the seller is located).
- This valuable (and heavily counterfeited) coin is not in a slab.
- The metal color looks like a typical Chinese counterfeit.
- The details are not sharp (which is typical for many counterfeits). Note the lack of details in LIberty's hair and the eagle's feathers.
I wish you would have asked about this coin before buying it. Oh, well.
Who knows? It may turn out to be genuine. And you may win the Power Ball tomorrow. Neither of those are likely to happen.
Good luck.
