Sorry, but there is no reason at this point in time to turn silver into a currency except to cause disorder in the economy. It is an industrial material used almost everywhere, including medicine.

As such, it's value is determined directly by supply and demand, and much of the demand is already in the form of fake coins sold by the hundreds of millions if not billions.

If silver were turned into a form of true currency, this would create a fake valuing system on it by creating a false demand on a limited supply product. Because of its widespread heavy use in industry it would cause a significant upheaval of industry across the board.

Gold is a much more useful form of currency, as its use in industry is quite limited with respect to its supply. It is used primarily in jewelry. Taking gold out of the system to turn it into currency would not significantly upend the industrial base. The amount of gold used in industry is very limited and any cost increase could be much more easily absorbed since many items are high value items that can absorb the fraction cost increase.
