get_spot_price
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).
calculate_melt_value
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.
calculate_coin_melt
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.
