What $100 in 1975 was worth — measured in gold

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

96.0%

of the US dollar's value, gone — measured in gold, since 1975.
It now takes 25.1× more dollars to buy the same ounce.

In 1975, $100 bought 0.62 oz of gold at $161/oz. Held as metal, that same money is worth $2,511 at today's gold price of $4,043/oz (spot as of 2026-08-02).

Same $100. Three rulers.

Measure	$100 from 1975, today	Multiple
Official story — CPI-U (BLS)	$623	6.2×
Money created — M2 money supply	$2,393	23.9×
In gold — honest weight, valued today	$2,511	25.1×

The gap between 6.2× (CPI) and 23.9× (M2) is official inflation understating the money actually created. The gap between 23.9× and 25.1× (gold) is the flight to hard money — gold outrunning even the printing.

1975 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.
