Should I trade my small gold bars in for a larger one?

It can make sense, because the premium per gram tends to be lower on larger bars, so a bigger bar tends to cost you less to hold per gram. We value your small bars at our buy-in price and take that off the larger bar at the shop price. The reverse, large to small, works the same way.

Why bigger bars tend to cost less per gram

Every bar carries a premium over the gold price. Part of that premium pays for making the bar, assaying it and handling it, and those costs do not grow in step with weight. A 100 g bar is not five times the work of a 20 g bar. So the premium per gram tends to fall as the bar gets larger. Our article on gold premiums over spot shows how it looks across our range.

This is a tendency, not a promise. Premiums change, and the price you can sell a bar for later depends on the gold price and on what we are paying then. Nothing here is a guaranteed return.

Our upgrade page shows what your small bars are worth towards a larger one, using today's figures.

Trade small bars for a large one

What this means when you sell later

When you bought small bars you paid a higher premium per gram on each one. A larger bar carries less premium for the same weight, so there is less of it to recover when you sell. Many people who build up gold with several small bars later trade them in for one large one for this reason. Our article on choosing between a 100 g and a 1 kg bar looks at the larger sizes.

The reverse: large to small

Some people go the other way. A large bar is harder to sell in part, because you can only sell the whole bar. If you may need to sell a little at a time, or give pieces as gifts, smaller bars are easier to use. We trade large bars into smaller ones in the same way, and you keep the flexibility you want.

How the trade-in is priced

We value the bars you bring at our buy-in price, then take that off the price of the bar you choose, at the shop price. You pay or receive the difference, and it is settled in one visit. There is no minimum. The figures move with the market, so they are live on the upgrade page and not repeated here.

A worked example

This example uses invented figures for 23 October 2026. They are not our prices. Say you bring five 20 g bars, 100 g in all, and our buy-in price for them comes to S$16,700. A 100 g bar at the shop price is S$17,300. You pay the difference of S$600 and walk out with one 100 g bar.

What you gain is a lower premium per gram on the gold you now hold. What you pay is the gap between our buy-in price and the shop price. Whether that works out for you depends on the figures on the day and on how long you plan to hold, so we show you the figures before you decide.

What to bring

The bars, with any boxes, cards or certificates you still have.
Your NRIC or passport. We check identity on every trade-in.

Trade-ins and sell-backs do not earn points. Jewellery and bars go on separate receipts. Walk in during opening hours, or message us on WhatsApp first.

Questions we are asked about this

Is a larger bar always cheaper per gram?

It tends to be. The premium per gram usually falls as bars get larger, but it can change, and we show the live figures on the page.

Will I make money by trading up?

We cannot promise that. A larger bar tends to carry less premium per gram, but what you get when you sell depends on the gold price and our buy-in price at that time.

How are my small bars priced in the trade-in?

At our buy-in price, which is then taken off the shop price of the larger bar. You pay or receive the difference.

Can I trade a large bar for smaller ones?

Yes. It works the same way in reverse, and is useful if you want to sell or give gold in smaller pieces.

Is there a minimum?

No.

Do I earn points on a trade-in?

No. Points are not earned on trade-ins or sell-backs.
