Commodities

What physical goods weigh in fine gold, monthly since 1960. The Transaction Database records what creative work cost in gold across history; this records what everything else costs in gold now. Why gold? The methodology explains.

Based on the gold price of September 2026.

Everyday goods, United States

Two United States series, kept because an hour of work and a dozen eggs are things people already have a feel for. Both come from the Bureau of Labor Statistics, which notes that its average-price figures, the eggs here, describe a single month better than they describe a trend.

A dozen eggs, US city average

Currencies

Imagine a loonie sitting on one pan of a scale. This is roughly how much gold you would sprinkle on the other pan to make it balance. It is a more useful way to hold the price of a currency than an exchange rate is, because the thing on the other pan does not move around.

Every figure is a monthly average, weighed against gold in the same month. One troy ounce is 31.1034768 grams. Each row's line traces that weight from 1960 to now, on a logarithmic scale.

Over time

The same measurement, month by month since 1960: what one unit of each thing weighed in fine gold. Where a series covers too much ground for a linear axis to show it, the axis is logarithmic and the caption says so.

An mmbtu of US natural gas, roughly a gigajoule. Logarithmic scale.
A tonne of Australian thermal coal.
A tonne of copper. Logarithmic scale.
A troy ounce of silver, which is metal measured in metal.
