No idea how pure that silver is, but if it's 100% pure it seems the monetary value today would be around 50 * $525 = $26,250. Of course the historical value is something completely different, if its provenance can be proven.
I'm glad it was presented to the authorities and not ... handled privately, heh.
I agree - and that's a 50 kilogram bar, ~110lbs. of silver, which is even more impressive. If there are many more, the treasure could be worth a tidy sum (though of course silver is not as exciting today as it was when Spain mined South America to support Europe's appetite for Chinese products like porcelain, silk, spice, and tea).
