    Bullion calculators

    Check what you're really paying for gold and silver, and what a pile of old dimes and quarters is worth in metal. Spot starts at today's price, and the numbers update as you go.

    Premium over spot calculator

    The premium is everything you pay above the value of the metal itself. Pick a product or describe your own, enter what you paid, and see how much of the price is metal and how much is markup.

    The weight is the piece's

    Enter the price you paid and the spot price to see the premium.

    How it's calculated
    • Pure metal = weight × purity (or the weight itself, when it's already the pure content) × quantity
    • Melt value = pure troy ounces × spot price
    • Dollar premium = total price paid − melt value
    • Premium % = dollar premium ÷ melt value × 100
    • Cost per pure ounce = total price paid ÷ pure troy ounces

    One troy ounce is 31.1035 grams. Bullion is usually stamped with its pure content (a Gold Eagle weighs 1.0909 oz but holds 1 oz of gold), which is why the presets enter the pure weight. More in how to calculate premium over spot.

    Junk silver calculator

    US dimes, quarters and half dollars dated 1964 and earlier are 90% silver. Enter their face value, or count the coins, to see how much silver they hold and what it's worth at melt.

    $ / oz t

    Enter a face value (or some coins) and the silver spot price to see the melt value.

    How it's calculated
    • Pure silver = face value × .715 troy oz (circulated) or × .7234 (uncirculated)
    • Melt value = pure silver × silver spot price
    • Multiple of face = melt value ÷ face value

    Every pre-1965 dime, quarter and half was struck at 90% silver in exact proportion to its face value, so $1 face of any mix holds .7234 oz new. Decades of wear shave a little off, so dealers work from .715. Silver dollars and 40% Kennedy halves hold different amounts and aren't covered here. More in junk silver explained.

    These calculators give estimates for information only and aren't financial advice. Melt value is what the metal is worth at the spot price you enter; what a dealer pays or charges will differ.
