Benchmark green coffee prices (commodity, not retail)
Monthly world benchmark prices in U.S. dollars per pound, from the IMF Primary Commodity Prices series on FRED (fetched 2026-10-23 00:59 CDT).
Home-roaster green coffee usually retails well above these benchmarks because of small-lot handling, shipping and quality premiums.
