I have owned this quite a while, and have never been able to nail down a value of this coin. The full date missing and the lack of any data on being a shipwreck coin bring it down, I know.
If you have the grade and the NGC # of the coin, you can look up pictures of graded coins. Helps to authenticate the coin and slab. https://www.ngccoin.com/certlookup/ From there he did a print screen and cropped out the reverse of the coin.
Most knowledgeable person on these things is Daniel Sedwick. His website is sedwickcoins.com. His email address is on his website. I emailed him for information on an old Reale I found (my avatar) and he responded same day and was just as nice as could be. He makes a living auctioning pieces like this. I’m sure he could get you dialed in on a value.
Yep. Sedwick is the go-to authority. Great coin. Easily worth four figures, I'm sure. Too bad the specific shipwreck provenance did not get recorded and put on the label, but so it goes.
