💰 Oracle bone glyph showed nuggets of metal under a roof or mold
金 originally depicted lumps of metal beside a casting mold; the bottom 土 hints at earth/ore. Meaning broadened from bronze/gold to metals generally, then to money and even ancient bronze percussion instruments.
金 — roof 亼 + two dots (metal nuggets) + earth 土
Originally a pictograph of metal nuggets buried in the earth beneath a covering, with the two dots representing pieces of ore. It first meant 'metal' broadly, then narrowed to 'gold' as the most precious metal, and by extension 'money'.
