A gold coin or bar is investment gold — often the purest gold you own. Unlike a piece of jewelry, which mixes gold with other metals and with "workmanship," an investment bar or coin shows a high purity and a precise weight, engraved on it. That is exactly what should earn you the most when you sell... provided you sell in the right place.

Do you hold a few gold coins, a small bar, an inheritance, and want to convert it into cash in Dakar? The process is simpler than for jewelry, but it has its own rules: purity, possible premium, authenticity. Knowing them keeps you from undervaluing a precious asset.
At Jayma Or, we regularly buy gold coins and bars in Dakar, in addition to jewelry and scrap gold. We test and weigh in front of you, we explain the price based on the world market rate, and we pay cash the same day. Here is how to get a fair price for it.
In this guide, you will learn:
- what sets investment gold apart from jewelry when you sell;
- how the value of a coin or bar is calculated;
- why authenticity is decisive here;
- how to sell something of high value completely safely.
Investment Gold vs. Jewelry: The Big Difference
The distinction is essential, because it works in your favor:
- A piece of jewelry contains gold mixed with other metals (75% for 18-karat, 87.5% for 21-karat), and its workmanship is not paid for when you resell.
- An investment bar or coin generally shows a very high purity, close to pure gold at 99.9% (24-karat), with a certified, engraved weight.
The result: for equal weight, your investment gold contains more precious metal than jewelry, and its value tracks the world market rate directly. That is precisely why it deserves a buyer able to pay as close as possible to that rate — not a jeweler's margin. To get a clear sense of the purity levels, see our article on the different types of gold.
How the Value of a Coin or Bar Is Calculated
The calculation rests on the same fundamentals as for any gold:
- The exact weight, often already engraved on the bar or standardized for coins, but always re-checked on a precision scale.
- The purity, generally very high for investment gold (24-karat / 999 in many cases).
- The day's rate for the gram of fine gold, which changes daily according to the world market.
The formula: weight × purity × price per gram = the value of your gold. Some collector coins may be worth a little more than their metal content alone (a "premium" tied to their rarity), but the basis is always the value of the gold. Check the day's rate shown on our home page to get your bearings before selling.
Why Authenticity Is Decisive
With investment gold, the question of authenticity matters more than with jewelry: coins and bars are subject to counterfeiting. A serious buyer therefore carries out transparent checks:
- Purity testing using reliable, non-destructive methods. Discover the methods for testing gold purity.
- Weight verification against the official weight of the coin or bar.
- Examination of the markings (hallmarks, serial numbers, any certificates).
These checks are not aimed at you: they protect both parties and guarantee that you are paid for real gold, at its fair value. Keep any original certificate or packaging: it makes the appraisal easier.
Selling Something of High Value Completely Safely
Coins and bars often represent large amounts. Security therefore comes first:
- Absolutely avoid improvised meetings with strangers: the risk (theft, fake bills, scam) is too great for this kind of value.
- Favor an established, professional buyer who tests and weighs in front of you.
- Bring an ID: for large amounts, verifying identity is an essential protection.
- Insist on cash payment, clear and immediate.

Frequently Asked Questions
Does a coin or bar sell better than jewelry?
For equal weight, investment gold contains more precious metal than jewelry and is bought as close as possible to the world market rate. So it often offers better value per gram.
Do I need the original certificate or packaging?
It is not required, but it makes the appraisal easier and faster. Without a certificate, a purity test determines the value precisely.
How do you verify that a coin is authentic?
Through non-destructive purity checks, a weight verification, and an examination of the markings, all carried out in front of you, fully transparently.
Is a collector coin worth more than its gold weight?
Sometimes, yes: certain rare coins carry a premium tied to their numismatic interest. The basis is always the value of the gold they contain.
How does payment work for a large amount?
Payment is made in cash the same day. For large amounts, other arrangements can be agreed; the simplest remains immediate cash.
