Reading a gold price board: buy, sell and the spread

Every gold board has two columns. Many first-time buyers read them the wrong way round.
Two columns, from the shop's side
- Buy: what the shop pays when you sell gold to it.
- Sell: what you pay when you buy gold from it.
The sell price is always higher. The gap is your cost if you buy and immediately sell back.
Units
| Unit | Equals |
|---|---|
| 1 chỉ | 3.75 g |
| 1 lượng (tael) | 10 chỉ = 37.5 g |
| 1 ounce (oz) | 31.1035 g |
Many boards quote per tael; the Kim Bảo Minh Châu website quotes per chỉ with grams. To convert a tael price to chỉ, divide by 10.

The cost of a round trip
Illustrative example: 9999 rings buy at 14.0 million VND per chỉ and sell at 14.3 million. Buy 5 chỉ and sell straight back:
- Paid: 5 × 14.3 = 71.5 million VND
- Received: 5 × 14.0 = 70.0 million VND
- Round-trip cost: 1.5 million VND, about 2.1%
Gold must rise by more than the spread before a buyer profits on sale.
World price converted
The Gold prices page includes world gold converted: the USD per ounce price turned into VND per chỉ at the exchange rate. The gap between domestic and converted world prices moves with local demand, import costs and policy.
