See e.g https://www.macrotrends.net/1380/gold-to-oil-ratio-historica.... Over 80 years (since 1946), the ratio held stable within 10-40 range, with a few brief spikes. The variance from the average held in a band [-2x, 2x], with a few brief spikes of ~ +-4x.
See also e.g. https://www.creditdonkey.com/gas-price-history.html for the raw price of gasoline, exponentially shaped. The increase over 80 years (since 1946, to match the ratio dataset) is 15x.
Extra wrinkle. The exponent of the exponential is not quite constant over time, currency can debase much faster than one would naively expect by extrapolating historical trends.
Edit. For completness, the BLS inflation index tracks a price inflation from 1946 to 2023 of, guess what, 15x. https://www.in2013dollars.com/us/inflation/1946
