Grimnar, as far as stumbling across stories of "suits of armor" found with "a body still in there", you gotta remember that treasure stories get emblished over time. If i had a dollar for everyone who stops me while detecting, to tell me of their "sure-fired-treasure" lead, I'd be rich

A story starts with a kernal of truth, and after a few years, gets turned into a whopper. I've even seen this psychology develop within the space of a week:
A friend of mine, during an old-town sidewalk demolition project, found what he thought was an antique gold amulet owl-shaped pendant thing. He showed it to a few of the construction workers who had let him hunt there. He mused to them "it might be gold, and the eyes of the owl look like jewels. It's probably very antique anyhow", etc.... That night he tested it, and it turns out it was not real gold, and the eyelets of the owl were just glass. About a week later, he was back on the same side-walk project, and this time, a new construction worker saw him detecting. After watching my friend for awhile, he finally got up the courage to come over and talk. He started telling my friend about how "the week before, this guy was here and found all sorts of old gold and coins, blah blah blah". My friend listened, and was thinking to himself, "gee that's funny, I've been on this project almost every day since it started, and I didn't see anyone else out here finding things like that! All I've gotten is a scruffy few barbers, a seated, some V's, etc..." As he listened the construction worker spin his "iron-clad" tale, the worker mentioned that one of the items this "other fellow" had found, was a solid gold owl pendant that was hundreds of years old!. At THAT, my friend realized the worker was talking about him

So he corrected the worker and told him "no, it wasn't 'armfuls' of coins, it was just a half-dozen or so. And no, the pendant wasn't solid gold, nor was it valuable", etc.. But the worker would not be dissuaded. He knew for a fact that his story was true, because he had heard it from first hand witnesses who had been there the previous week. Doh!
You see how that works Grimnar? The human mind wants so hard to believe in the "lead" (lest you "miss out"), that suppositions turn out to be believed without question or scrutiny. So too is it with cache stories, suits of armor stories, etc... Even when it's supposedly "first-hand", you read more deeply, and it's "someone who told someone who told.... " etc... Or even if it's old microfilm newspaper clippings, you have to ask yourself "where did the reporter get his info?" By taking the word or whomever he was interviewing, which is subject to whims of interpretation, etc.....
Yes there are caches that are really found, and probably have been suits of armor found in a cave or canyon before (that just magically were never seen or explored before now). But you have to keep in perspective, that all it takes is one to be found, before it is morphed into many many other variations, rumors, legends, etc.....
For pix of the Spanish era coins, buttons, relics, etc... that I have found, check out the Kinzli California forum. To get to the main page, you have to sign up. But it's easy (just pick a name and a password). Once there, just do a search under all my posts for the past several years, and you'll see many pix of reales, buttons, etc.....
