Questions
Before you buy or sell
How do I read a hallmark?
The three-digit stamp is the fineness in thousandths: 585 means 58.5 % gold, 750 means 75 %. Karat is the older scale, 24 parts being pure. Coins and bars carry 999 or 999.9, jewellery mostly 333, 585 or 750.
What is a troy ounce?
The unit bullion is priced in: 31.1035 grams, a little more than the kitchen ounce of 28.35 grams. Spot prices are quoted per troy ounce, dealers in Europe usually per gram.
Why do buyers pay less than the spot price?
Spot is the price of pure gold in a wholesale market. A buyer deducts the base metals in your alloy, then a margin for melting, assaying and resale. For coins and bars the deduction is small; for scrap jewellery it can be sizable, which is why quotes differ so much.
Should I sell to a cash-for-gold shop?
Only with a written offer from at least one other buyer in hand. The city editions explain which quotes are fair in Berlin, Munich, Düsseldorf, Marbella and Mallorca.
Is a bullion coin worth more than its gold?
Usually a few percent more, the premium. Krugerrand, Maple Leaf and Philharmonic trade close to melt value; rare years and proof strikes far above it. Never sell a coin by weight before checking the date.
