World Produces Twice As Much Silver As We USE According to the Silver Institute:
The world produces about 1 BILLION ounces of silver per year.
We only USE about 500 million ounces.
The other 500 million ounces per year are stored (for future use) in one form or another including bars and coins
The world is FLOODED in thousands of tons of excess stored silver and the massive piles of stored silver are growing each year
