I suppose if I ever do find something, I will have to actually break open the chest and pour the gold bars directly on to your head before convincing you... and even then, "maybe"....
Neither you nor I have ever seen Mel Fisher's museum of stuff. Nor have either of us seen the museum's of treasures excavated @ the Egyptian pyramids. Yet we both believe the stuff was found (without the stuff being poured over our heads).
T'net's "Today's find" forum is FILLED DAILY with show & tell, by md'rs and th'rs eager to show off their latest trophies to each other. Yes .... even some valuable stuff. Yes... even some caches now and then. And no: You and I don't have any reason to disbelieve them.
But I can already see the come-back retort lines (since I've been here before): "Those T'net today's finds column is all small peanuts. If someone found a big ticket item, they'd keep quiet. Because they're afraid of the IRS, thieves, and claim-jumpers. Right ?
So as you can see, it's not that I "wouldn't believe", it's just that all these yamashita treasures being found all the time are simply never making the news and show & tells. See the vicious circle ? And if you ask long and hard in the Phillipines, of all the hardcore hunters of the last 40 yrs., I'll bet none of them have seen a single item of this supposed treasure. Oh sure they'll allude to stories they heard, of someone they knew who saw something. And if you hunt down THAT person, it will turn out that *they too* did not actually "see" anything either. But instead got it on good authority from so & so. So you hunt down THAT person . And guess what ? They too never actually saw anything either. But not to worry, since they got it on good authority from .... Do you see the infinite regression ?
If you study the news worldwide, there are caches being found, that *do* make the news. Eg.: a farmer accidentally hits it with his plow. A construction worker accidentally digs it up with his backhoe. A couple walking their dog in the Sierra Nevada foothills finds rusting cans filled with gold coins. Mel Fisher finds the Atocha. Etc... etc... But alas: When it comes to Yamashita, they're all hush hush. Right ? So there's really no opportunity for a skeptic to believe in the first place, since none will ever be shown.
I admit: a few times some pictures surface of piles of gold bars someone says were Yamashita's found goodies. But when you go to correspond with the person who's sharing that/those photos on T'net, it's invariably not THEIR find. They just got the pix from somewhere else (typically a National Enquirer type news rag from the Philippines, can't doubt that, right ?).
