Which is  decreasing in value?

The author's opinion:

Paper money has been losing value for decades. Case in point; Candy bars used to cost 5 cents, now they cost $1.00.  In 1974 a Pontiac Trans Am Cost $2500.00, today a Camaro can cost $30,000 to $50,000.00. Inflation erodes the value of the dollar 2 to 3 percent a year.

The author's opinion:

Silver Bullion's value fluctuates.

Ownership of Silver is an efficient strategy to protect overall Net Worth. 

When paper money is no longer accepted, precious metals become the currency of trade. 

The author's opinion:

Numismatic coins are collector's items. Their value is based upon an accepted grading system.
