Hello,

I have this coin from 1639, I was told it's from a shipwreck, I am looking for a value, its 26.6g can anyone grade this coin for me?

What metal is it? It would be hard to grade, even knowing the metal, from only a picture. It being supposedly from a shipwreck has little to do with it though. Visiting a numistmatist, and they are readily available nowadays, would be more beneficial to you.

Sorry, it's Silver. From a shipwreck of the cost South Africa.
