I don't know if the physical quantity matters as much as the cost per ounce of the gold to maintain the standard. I think the fact that production is falling is possibly a key as well, the dollar has to be pegged to something of real value. Things which are rare hold real value from a supply demand sentiment.
I think we are probably a likely take over target if they can prove up reserves. And I don't know what that would do for sp, I assume a rise, but I just don't know.
