Hunt Brothers vs. Japan

In the 1970s the Hunt Brothers were able to drive the price of silver up to about $50/oz.  With around $1 billion they controlled over half the world's silver.   There is many times the amount of money in circulation today as back then.   The stockpile of above ground silver is smaller than back then.   Imagine if Japan gets hyperinflation, so the Yen is not a good store of value, and many people in Japan start buying silver as a store of value.   The price of  silver could go way up.
