bul·lion /ˈbʊljən, ˌjɑn/
 金銀,金銀塊,純金
 Bul·lion n.
 1. Uncoined gold or silver in the mass.
 Note: ☞ Properly, the precious metals are called bullion, when smelted and not perfectly refined, or when refined, but in bars, ingots or in any form uncoined, as in plate. The word is often often used to denote gold and silver, both coined and uncoined, when reckoned by weight and in mass, including especially foreign, or uncurrent, coin.
 2. Base or uncurrent coin. [Obs.]
 And those which eld's strict doom did disallow,
 And damm for bullion, go for current now.   --Sylvester.
 3. Showy metallic ornament, as of gold, silver, or copper, on bridles, saddles, etc. [Obs.]
    The clasps and bullions were worth a thousand pound.   --Skelton.
 4. Heavy twisted fringe, made of fine gold or silver wire and used for epaulets; also, any heavy twisted fringe whose cords are prominent.
