I do not know enough about them to verify it sir, just know most sea salvage silver has to be looked at by real pros in order to see if authentic. I know there are some pros on these on CT, hopefully they can comment.
@medoraman . While these can be had at many novelty stores and come with COA's, they are replicas and these certificates are a dime a dozen. But they can still be in this condition and be completely authentic. Best to research this subject before jumping the gun with quick replies.
@Jimm but you COA is worthless, and is not a guarantee. Send it back for a refund if you can. @CHARLES GINETTO @Morgandude11
These COA's can be printed in seconds, and the crude method of producing these coins make them easily counterfeited.
Good comment. I have quite a few of these, and the OP coin does appear genuine.
El Cazador. Sorry I haven't taken images to share. The whole story about the chap who found the coins in his fishing nets is quite interesting.
I have one El Cazador 8 Reales and it's slabbed. I would never buy a raw one. Far too many fakes out there. The history behind the ship and how they found the wreck is fascinating for us history buffs.
This coin, I am very confident has spent 170 years at the bottom of the Mediterranian, just off the coast of Mallorca, and not in Cardigan Bay as the write up in the Bulletin Numismatique No 59 erronously reports.
It was probably from a costal trader out from Marseille lost around 1837 as the coin (and many others) are almost 'as struck'
Must have been extremely well protected underwater, like in a sealed cask or something. Saltwater leeches first the copper ions from silver coins. This is extremely well known, in fact the Romans used this fact in the 3rd century to create their shiny, silver looking 5% silver coins. In the sea for 170 year NO silver coin, lying loose, would not lose quite a bit or weight and have a granular surface.
Weight 24.41 g against 25.0 (book)
People usually repeat what they have read or heard elsewhere. I am just supplying evidence, which I am very confident is accurate. Philippe BOUCHET who examined the find and wrote the article was a well respected French Numismatiste.
I do not doubt your information sir. Thanks for the weights, showing some was lost. We do not really know how they were underwater, and there is a lot of them, so I am still supposing in a fairly small container, all together, and if not a lot of current, (because in a container), it seems very reasonable. Same as ancients found in a pot or bags of morgan dollars stored for a century. The more contained the coins are together, and the more coins in a group there are, the less each coin is affected. Morgan dollar bags would have bright white, untoned coins in the middle, and only the ones along the edges were toned.
Take the same coin and throw it on the seabed, and the weight loss and surface condition would be much different. I have friends who scuba dive, and silver coins they find randomly in the ocean are in MUCH worst shape being younger than the coin you depicted sir.
My comment about how the Romans surface leeched 5% silver flans was also from a friend who strikes medieval style coins. He replicated the process, and I was there when he took flans he leeched in saltwater that looked like pure copper, but upon striking the ions of silver left on the surface melted and coated the coin with a thin silver plating.
