Silver is considered to be the money, of the ages. It's history is documented for 6 thousand yrs. Gold was kept in storage for large purchases, but Silver was used for everyday commerce. Silver as the money of choice was due to several natural characteristics; it is portable, divisible, internationally recognizable, indestructible, and precious*.
There is but one Kingdom, that will last forever; all others will rise, debase their money, then eventually fall.

Approximately 80% of the Silver mined is used for industrial purposes. Ten percent for jewelry, and ten percent for coins. Silver represents the middle class, good for money and a storage for labor. Since 1973 in America, the middle class continues to shrink;this coincides with the debasement of Silver and the gold standard of 1973.
