Precious Metals Reference & Buying Guide
What is a Troy Ounce vs. Standard Ounce?
Precious metals are weighed in Troy Ounces (oz t), which are heavier than standard Avoirdupois Ounces (oz) used for food. One troy ounce is exactly 31.1035 grams, whereas a standard ounce is only 28.3495 grams. Always ensure your commodity weights are converted to troy measurements.
How does Karat Fineness affect value?
Karat represents gold purity on a scale of 24. 24K gold is pure gold (99.9% fine). 18K is 18 parts gold and 6 parts alloy (75% pure), and 14K is 14 parts gold and 10 parts alloy (58.3% pure). When calculating melt value, we multiply the total weight by the purity percentage to isolate the weight of the pure gold.
What is spot price and dealer premium?
Spot price is the current global market rate at which a troy ounce of raw refined metal is trading. Dealers buy and sell bullion at a markup called the "Premium." This premium covers their refining, minting, shipping, and operational margins, usually representing a 2% to 15% charge.
A Worked Example
Say you have a 14K gold chain weighing 20 grams. Because 14K is 58.3% pure, only about 11.66 grams is actual gold. At a spot price of $2,400 per troy ounce — roughly $77 per gram — the melt value is about 11.66 × $77 ≈ $900.
A dealer buying back a few percent under spot might offer around $810. Knowing the melt value first is your best protection against a lowball quote — and it's why the calculator separates pure metal content from total weight before applying any premium or discount.
Frequently Asked Questions
Is gold a good hedge against inflation?
Gold has historically held its purchasing power over long periods and often rises when confidence in currencies falls. It pays no interest or dividends and can be volatile, so it's typically used as one part of a diversified portfolio.
Should I buy coins or bars?
Bars usually carry lower premiums per ounce and suit larger investments, while coins are more recognizable, easier to sell in small amounts, and sometimes carry collectible value — at a higher premium.
How much below spot will a dealer pay me?
Dealers buy back below spot to make a margin — often a few percent under for common bullion, and more for jewelry or obscure items. Getting quotes from multiple buyers helps you sell closer to spot.
