1715 Treasure Coast find.

I can't speak to the authenticity of the coin, but I can tell you if you've found real spanish silver, that's a big coin. At least 4 reales.

Seems to me that silver from 300+ years ago would look more tarnished, too, but that doesn't mean much, given we have no idea the conditions it sat in, until it was brought up.

Check for silver by running a STRONG magnet against it (with a piece of paper between). If it's silver, it'll slightly repulse the magnet against the rub direction. Do this with a known silver coin, so you know what to feel.

You can also spit on it, and wrap it in foil, and 30 seconds later, open it... if it stinks to high heaven, there's silver content. (creates sulfides).

Cheers,

Skippy

That's a heck of nice find!

If that's genuine, it's a **really** amazing find - congratulations!!!

That said (and I'm just guessing here) - it does look a lot like toy pirate treasure coins I've seen (like these)

Don't mean to be a buzzkill - hopefully I'm wrong.

I would

Check with Scoundrel, he was one of the diver's that found the big hoard of Gold coin's down their, he find's the silver cob's on , and off, he would probably know with some close up shot's, Earl
