It’s a strange thing. I could see an eccentric billionaire buying it one day and digging up half the island.
Ping.
I don’t think those two brothers with a reality show on History channel that features all the digging by them and others are billionaires, but it seems that just about everyone who lives there spends time treasure hunting, and has for about the last 200 years-and everyone has a different theory about what the treasure is and who put it there-Knights Templars/Masons, Aztecs escaping from the Spanish, 17th-18th century pirates, etc.
Since there has been no real treasure, in the sense of substantial gold, silver or precious gems found in all that time, maybe if anything was put there for safekeeping, someone came and retrieved it shortly thereafter-or maybe it is just a story made up to explain the historical artifacts there-I think those are “real” treasure, but that is just my opinion...
