About 21,6 karat
900 means 90,0% pure gold. Klassisk møntguld, fx danske 20 kr. The rest of the alloy is typically copper, silver, zinc or nickel, which determines the colour: more copper gives rose gold, while more silver and palladium gives white gold.
Where do you find the stamp?
Look for the three small digits on the inside of a ring, on the clasp of a chain, or on the back of a brooch. Older Danish pieces may instead be stamped with a karat mark, e.g. «14 K». If the stamp has worn away, a jeweller can test the purity in a few minutes.
What affects the price?
Only two things: the spot price of pure gold and your weight. Design, brand and age usually mean nothing when selling for melting down — only if the piece has its own collector's value.

Tips before you sell
- Weigh your items at home on a scale with two decimals and write the weight down.
- Sort by stamp – never let a buyer weigh mixed purities as the lowest fineness.
- Get at least two or three written offers and compare them in kroner per gram.
- Remove stones, pearls and steel clasps, or make sure they are deducted from the weight.
- Check today's price on this page right before you visit the buyer.

Questions and answers
What does the 900 stamp mean?
900 means there are 900 parts pure gold per 1,000 parts of metal — in other words 90% pure gold. The rest is other metals that make the alloy harder and more durable.
How do I calculate the price of 21,6 karat?
Multiply the spot price per gram of pure gold by 0.9 and then by the weight in grams. The calculator on this page does this automatically at today's rate.
Do I get the spot price for 21,6 karat when I sell?
No. A buyer typically pays 70–95% of the metal value, because the alloy has to be melted down and refined. The larger the quantity, the better the price per gram you can usually negotiate.
Why does the 900 price change during the day?
The price follows the international spot price of gold, which trades around the clock in US dollars. Movements in the dollar exchange rate also affect the price in Danish kroner.
How can I tell whether my 900 gold is genuine?
Check the stamp with a magnifying glass, test with a magnet (gold is not magnetic) and have a jeweller or buyer do an acid or XRF test before you sell.
Should I sell several purities together?
Sort your items by stamp and get a price for each purity. That way you can check that the buyer pays the correct pure-metal value for every item. The scrap gold calculator can add up several purities at once.
