No documented importance? The Spanish documented every ship.There are shipwrecks all up and down the east coast from the Florida Keys to Cape Canaveral. There are only a couple missing 1715 ships and I just dont happen to believe any of them could be that far south.
The hurricane hit the fleet and only one ship survived intact. Its very well documented. They sent to Havanna for help. The rescue is also very well documented. I dont remember the whole story. The only confusion is which inlet the southernmost shipwreck was at near the Ol Bleachyard. I seriously doubt the Bleachyard could be any further south than St Lucie Inlet or Jupiter at the very most. The gulfstream flows north and they didnt travel too far apart for fear of pirates.
No way a ship carrying treasure would be undocumented and lagging so far behind. It just doesnt make sense. They waited in Havanna to sail together because it was of utmost importance for protection. The problem is they waited too long and sailed the wrong day in hurricane season.
The coins being found by oltimers are probably not dated 1714-15. That would be proof . There are many shipwrecks up and down the coast from the 1500S-1600S Spains heyday, not 1700s IMO.
