As many others have said, it would be beneficial for all joining to read all of the posts thus far so as to at least be up to speed with discoveries and also not just repeat what has already been covered.
Of course, nothing is confirmed. But what most consider to be the significance of "within the text you have the key, for the one that is missing you did not see" is the fact that the letter 'Q' appears NOWHERE in the entire book, not just the page of blocks. In fact, many have already surmised that the reason the 'jibberish' blocks are on that page of blocks in addition to the line of the poem is to fill out the entire alphabet except for the letter 'q', another clue that Q is the one that missing or, in other words, "the one piece nary". Maybe not, but it does make sense.
As for revelation of whether tokens have been found...unless all the tokens were found in the first couple of weeks or so, I suspect Stadther would be more than happy to announce that one or two had been found. That would stimulate far more sales and interest in the book than if three years went by without any word of any winners, wouldn't it?. People lose interest pretty quickly, but the announcement of a winner every so often would rekindle interest and PR.
Finally, I personally believe there is one system for finding all 13 jewels. Doesn't the fact the jewels are scattered all over the United States in vast public domains reduce the chance one person will find all the jewels, even if they discover the key to finding one? That's a lot of time, money and travel for one person to undertake. A friend and I have a system using the clues in the book that so far is showing consistent in identifying highly likely locations for at least 6 or 7 of the jewels. I just can't get away to go look --aaagh. Still even knowing what I think I know, a location is narrowed down maybe to a few hundred square yards. Still if I find one... will I stop there...
Deciphering the poem, finding out which fairies are the ones to listen to, idnetifying which location pertains to which fairy etc is such an undertaking in and of itself, I think that even if I am right, someone else will get to one or several of the tokens before me.
By the way,, I've not seen any discussion here about the possibility the 5X5 code of numbers could pertain to a Magic Square... where all the numbers in all columns, rows and diagonals add up to 65 (which, interestingly enough, are the first two numbers in that line of numbers located at the beginning of the book). If there are numbers hidden in the book that are higher than 25, connecting the letters A-Z to those numbers' positions in a magic square might yield something?
