Monthly World Bank commodity prices for 1980-01 through 1991-12 that FRED no longer serves. FRED deleted 1980-01..1989-12 from all eight series on 2019-07-23 and 1990-01..2002-12 on 2026-01-22, then restored only 1992-01..2002-12 on 2026-03-24, so 144 months are absent from every current pull. Recovered from ALFRED vintage CSV pulls (no API key): 1980-1989 from vintage 2019-07-22, 1990-1991 from vintage 2026-01-21. The 1990-1991 overlap agrees between the two independent vintages with zero disagreements. Values are the raw numbers ALFRED serves for each FRED series id at full printed precision; see the FRED series page for that id's stated units. 8 series x 144 months = 1152 rows.
