    ABCDEFGHIJKLMNOPRSTUVWYZ

    A

    Allocated Storage
    A storage arrangement where specific, identified bars or coins are set aside for the investor. The metals are segregated and belong solely to you, not commingled with others' holdings.
    Ask Price
    The price at which a dealer is willing to sell precious metals. Also known as the 'offer price.' The difference between ask and bid prices is the spread.
    Assay
    A test or analysis to determine the purity and quality of precious metals. Assay certificates verify the metal content of bars and coins.
    AISC (All-In Sustaining Cost)
    A mining industry metric that measures the total cost to produce an ounce of gold or other metal, including direct mining costs, sustaining capital, and corporate overhead. Used to evaluate mining company profitability.

    B

    Bid Price
    The price at which a dealer is willing to buy precious metals from you. This is typically lower than the ask price.
    Bullion
    Precious metals in bulk form, valued primarily by weight and purity rather than form. Includes bars, ingots, and coins with little to no numismatic premium.
    Bullion Coin
    A coin minted from precious metal, valued primarily for its metal content rather than rarity or collectibility. Examples include American Gold Eagles and Canadian Maple Leafs.
    Backwardation
    A market condition where the spot price of a metal is higher than the futures price. In precious metals, backwardation can signal physical supply tightness or strong immediate demand.

    C

    Carry Trade
    An investment strategy involving borrowing at low interest rates to invest in assets with higher returns. Central bank policies affect carry trades, which can influence gold prices.
    Central Bank
    A national institution that manages a country's currency, money supply, and interest rates. Central banks hold gold reserves and their buying/selling significantly impacts gold prices.
    COMEX
    The primary futures and options market for trading metals like gold, silver, copper, and aluminum. Part of the CME Group, it sets benchmark prices for precious metals.
    Custodian
    A financial institution that holds and safeguards assets on behalf of clients. In Gold IRAs, a custodian is required by the IRS to hold the physical metals. Learn more in our Gold IRA Investment Guide.
    Contango
    A market condition where futures prices are higher than the current spot price. This is the normal state for most commodity markets and reflects storage and financing costs.

    D

    Deflation
    A decrease in the general price level of goods and services. While gold is often seen as an inflation hedge, it can also perform well during deflationary periods as a safe haven.
    Depository
    A secure facility where physical precious metals are stored. IRS-approved depositories are required for Gold IRA storage.
    Dollar-Cost Averaging (DCA)
    An investment strategy of buying a fixed dollar amount of an asset at regular intervals, regardless of price. This reduces the impact of volatility over time.

    E

    ETF (Exchange-Traded Fund)
    A security that tracks the price of an underlying asset and trades on stock exchanges. Gold ETFs like GLD and IAU provide exposure to gold prices without physical ownership. Compare options in our Physical Gold vs ETFs Guide.

    F

    Face Value
    The nominal value stamped on a coin by the issuing government. For bullion coins, the face value is typically much lower than the actual metal value.
    Fiat Currency
    Government-issued money not backed by a physical commodity like gold. The value is based on trust in the issuing government. All major world currencies are currently fiat.
    Fineness
    The purity of precious metal, expressed as parts per thousand. For example, .999 fine gold is 99.9% pure gold.

    J

    Junk Silver
    Pre-1965 U.S. coins (dimes, quarters, half dollars) that contain 90% silver. Called 'junk' because they have no numismatic value beyond their silver content. Popular for their recognizability and divisibility.

    K

    Karat
    A measure of gold purity in jewelry. 24 karat is pure gold; 18 karat is 75% gold. Not to be confused with 'carat,' which measures gemstone weight.

    L

    Legal Tender
    Currency that must be accepted for payment of debts. Government-minted bullion coins often have legal tender status despite being valued for their metal content.
    Liquidity
    How quickly an asset can be converted to cash without significantly affecting its price. Gold is considered highly liquid due to its universal recognition and demand.
    London Fix
    The benchmark gold price set twice daily by the London Bullion Market Association (LBMA). Used as a reference price for gold transactions worldwide.

    Melt Value
    The intrinsic value of a coin or bar based solely on its metal content at current spot prices. Bullion products typically trade close to melt value, while numismatic coins trade at premiums above it.

    N

    Numismatic Coin
    A coin valued for its rarity, historical significance, or condition rather than just its metal content. Premiums can be significantly higher than bullion coins. Understanding tax implications is important—see our Tax Guide for Precious Metals.
    Numismatic Premium
    The additional value of a coin above its melt value, based on rarity, condition, historical significance, or collector demand. Can range from modest percentages to multiples of the metal value.

    O

    Ounce (Troy)
    The standard unit of weight for precious metals. One troy ounce equals 31.1035 grams, slightly heavier than a regular (avoirdupois) ounce of 28.35 grams.
    Open Interest
    The total number of outstanding futures or options contracts that have not been settled. High open interest in gold or silver futures indicates active trading and can signal market sentiment.

    PGM (Platinum Group Metals)
    A group of six metallic elements: platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals share similar properties and are often found together in ore deposits. Platinum and palladium are the most commonly traded for investment. See our Platinum and Palladium investment guides.
    Planchet
    A blank metal disc that is struck by dies to create a coin. The quality of the planchet affects the final coin's appearance and, for collectible coins, its grade and value.

    Proof Coin
    A specially minted coin with a mirror-like finish, produced using polished dies and planchets. Typically sold at higher premiums for collectors.
    Purchasing Power
    The value of money in terms of what it can buy. Gold is valued for preserving purchasing power over long periods as fiat currencies lose value to inflation. Learn how metals protect wealth in our Wealth Preservation Guide.
    Physical Delivery
    The actual transfer of physical metal to fulfill a futures contract, as opposed to cash settlement. Most futures contracts are closed before delivery, but the option for physical delivery supports price integrity.

    R

    Rollover

    In options trading, the predetermined price at which an option holder can buy or sell the underlying asset. For gold options, the strike price determines profitability relative to the spot price.

    T

    V

    Vault
    A secure storage facility for precious metals. Professional vaults offer insurance, security, and auditing for stored metals.

    The market development organization for the gold industry, funded by leading gold mining companies. Provides research, data, and promotes gold demand through initiatives like gold-backed ETFs.

    Y

    Yield
    The income return on an investment. Physical precious metals generate no yield (they don't pay dividends or interest), which is a key consideration when comparing them to income-producing assets.

    Z

    Zero-Coupon Bond
    A bond that pays no periodic interest but is sold at a discount to face value. When real interest rates are low or negative, gold becomes more attractive relative to zero-coupon bonds.
