Bullion
Precious metals in bulk form, typically bars or ingots, valued by weight and purity rather than form.
Bullion is the purest form of investment metal. Gold and silver bars are cast at .999 or .9999 fineness. Bullion trades at small premiums (1-3%) over spot price. Coins are also considered bullion if valued for metal content rather than rarity. Bullion is the most cost-effective way to own physical metal.

Premium
The amount above spot price that buyers pay when purchasing physical precious metals.
Premiums cover: fabrication costs (minting coins, casting bars), distribution and dealer margins, and supply/demand for specific products. Premiums range from 1-3% for large bars to 5-15% for small coins. During high demand, premiums spike. Premiums are lost when selling back (you receive near spot price).
ExampleGold spot: $2,634, 1 oz coin purchase price: $2,710 (3% premium)
