What $100 in 1980 was worth — measured in gold

The price of gold didn't get more expensive. The value of the US dollar fell.

84.8%

of the US dollar's value, gone — measured in gold, since 1980.
It now takes 6.6× more dollars to buy the same ounce.

In 1980, $100 bought 0.16 oz of gold at $615/oz. Held as metal, that same money is worth $657 at today's gold price of $4,043/oz (spot as of 2026-08-02).

Same $100. Three rulers.

Measure	$100 from 1980, today	Multiple
Official story — CPI-U (BLS)	$407	4.1×
Money created — M2 money supply	$1,497	15.0×
In gold — honest weight, valued today	$657	6.6×

The gap between 4.1× (CPI) and 15.0× (M2) is official inflation understating the money actually created. The gap between 15.0× and 6.6× (gold) is the flight to hard money — gold outrunning even the printing.

1980 in the fiat story

Gold touched $850 in January 1980 — the crescendo of the first post-window decade — and Paul Volcker answered with 20% interest rates. It was the one era in the fiat period when the dollar was defended with real pain, and it bought the system two decades of credibility.
