What $100 in 1978 was worth — measured in gold

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

95.2%

of the US dollar's value, gone — measured in gold, since 1978.
It now takes 20.9× more dollars to buy the same ounce.

In 1978, $100 bought 0.52 oz of gold at $193/oz. Held as metal, that same money is worth $2,091 at today's gold price of $4,043/oz (spot as of 2026-08-02).

Same $100. Three rulers.

Measure	$100 from 1978, today	Multiple
Official story — CPI-U (BLS)	$514	5.1×
Money created — M2 money supply	$1,743	17.4×
In gold — honest weight, valued today	$2,091	20.9×

The gap between 5.1× (CPI) and 17.4× (M2) is official inflation understating the money actually created. The gap between 17.4× and 20.9× (gold) is the flight to hard money — gold outrunning even the printing.

1978 in the fiat story

Freed from its anchor, the dollar spent the seventies proving why the anchor had existed. Two oil shocks, double-digit CPI, and gold running from $35 toward $500 — not because metal changed, but because the measuring stick did.
