At the start of 1985, 1 ounce of gold bought 215 pounds of coffee.

At the start of 2015, 1 ounce of gold bought 740 pounds of coffee.

Right now, 1 ounce of gold buys about 780 pounds of coffee.

In other words, if you're spending gold to buy coffee it's been getting cheaper and cheaper. Only if you're spending paper faces has it been getting more and more expensive.
