As we know, the value of any piece is really whatever we can get someone to pay for it, if that's your goal. But just as some kind of starting point, if I did this right, the market value of the gold itself would be around $900.
...Roughly, gold is at about $1,790 per ounce today. That's for pure gold, or 24k.
Ah okay, gotcha. I was thinking it was something a hobbyist made, since it's rough hewn and doesn't have the carat weight marked on it. But it's exciting to consider that it may have come from an ancient shipwreck or something along those lines!
Hopefully, someone with knowledge in that area will come along.
