Hey Everyone!

I recently found this at a garage sale in Florida mixed in with costume jewlery. No markings indicating gold but I believe it’s 14k. With that being said do you think this is a real Spanish cob and if so does anyone know what period? Looks like there is wear from salt water. Wondering if it could be from the Atocha or another shipwreck!? Crazier things have have happened on here. Any help would be greatly appreciated. 63C85CB3-40E5-4F0B-9649-4F4DBC824BFD.webp82A78BB1-DA7D-46AE-A201-DBE71B06ACD0.webp1253FE68-B189-42C8-A82F-68DAF33F14FD.webp
 
My educated guess is that it is a sand cast from a genuine royal. The bezel is likely 14K. There is enough detail to pass a cursory glance as real, but when you look at the details enlarged, you see voids in the devices that shouldn't/wouldn't exist. Salt water corrosion will evenly corrode a surface, but it doesn't eat away metal while leaving the surrounding metal untouched. What you see on the surface with tiny holes is evident from air bubbles in a casting.

Thanks Diver_Down! Any idea what period this a copy of?
 
It is a nice looking piece. Nice find.
 
The original was an early 1600's (Atocha time frame) Mexico City piece. Again, I could be wrong, but I don't think so as I just looked through your pictures again and can identify 10 problem areas without even counting the rice crispy effect. I wish I knew how to do the drawing on pictures that you see so often by the younger generation as it would be a good learning tool.
 
My experience making jewelry is that Sand casting gives you a stippling surface and not bubbles , I have many cob coins with uneven corrosion due to proximity to other metals and or coins. Sand casting doesn’t give you much detail.
