You can also thank him for the fingerprints :)

paxbrit is right re return policy.

Impossible to say so from screen pictures, but the overall appearance, luster and patination induces some doubt in my mind, that there is a possibility that it is a centrifugal pressure cast copy. Should be checked.

I know that really good copies have been made of nice European crown sized coins, of European origin. Davenport also suggests this in various places in his books. I have been shown a few examples of centrifugal pressure cast copies, by a leading coin public auctioneer.
Nevertheless, most of me says 'genuine' at this time. I have to admit: it does really look like a desirable coin.

XRF testing and comparative pictures of genuine alongside for us to examine, would be of great help. Exact weight diameter and alloy should be checked against genuine.

Looks OK to my eye but if you do get the coin, closer examination is advisable.

As for grade, I'd agree that this is an AU55-58 coin which has been most likely dipped. Assuming there is luster on the piece it would grade in that range.
