Looks like an early die state as the knob is small. Coin was not listed as knob variety. I thought $27 shipped was a decent price for what looks like a vf something coin. Little verdigris looks like it should come off with verdicare. https://www.ebay.com/itm/3545209312...=true&nordt=true&rt=nc&_trksid=p2047675.l2557
Did you ask the seller to show you the coin's reverse side? The obverse has a few nicks and a bit of corrosion but otherwise it looks good. If it's not what you expect eBay has a great return policy. Good luck and thanks for sharing.
