  • calculate_coin_meltFree

    Calculate the melt value of junk silver coins (constitutional silver) at the current silver spot price: US 90% pre-1965 dimes/quarters/halves/dollars, US 40% Kennedy halves (1965–1970), US 35% war nickels (1942–1945), Canadian 80% (1920–1966/67) and Canadian 50% (1967–68) coins. Provide the coin type plus either a quantity of coins or a total face value (e.g. face_value 2.50 for a roll of dimes). Returns total actual silver weight (ASW) in troy oz and grams, and melt value in USD and CAD.

  • calculate_melt_valueFree

    Calculate the melt value (intrinsic bullion value) of silver or gold from weight and purity — e.g. sterling silver flatware, .999 rounds, scrap gold. Returns melt value in both USD and CAD plus the fine metal weight. Purity is a fraction: 0.925 = sterling, 0.999 = fine silver, 0.9 = US coin silver. Weight units: g (grams), ozt (troy ounces), oz (avoirdupois ounces — postal-scale ounces).

  • get_spot_priceFree

    Get the current spot price of silver and gold in USD and CAD per troy ounce. Use this to answer questions about the silver spot price, gold spot price, or the USD→CAD exchange rate used for melt value calculations. Prices are live, cached up to 15 minutes. All prices are per troy ounce (ozt).
