The world price is the same for everyone; what sets professionals apart is the margin applied to that price. ## The principle: fine weight times the price Buying back silver means assessing how much pure metal an item contains, then valuing it at the current price. The basic formula is always the same: the **fine weight** (total weight × fineness) is multiplied by the day's silver price. An item in 925 silver contains 92.5% pure metal; an item in 800, 80%. The silver price is a world price, quoted in dollars per troy ounce (31.1035 g) and then converted into euros per gram. It is identical for a private seller in Paris or a dealer in Lyon. Our [silver buyback](https://meilleur-rachat-argent.fr/en/silver-buyback/) page lets you compare professionals near you rather than relying on a single offer. ## What makes offers differ between professionals Since the price is common to all, the difference between two offers comes from the **margin**, also called the buyback rate. A professional quoting 90% of the price will pay you more than another at 75%, for identical metal. This margin covers assay costs, melting and profit. The nature of the item also matters (bar, silverware, coin), along with the presence of official hallmarks that ease authentication, and general condition. For a lot of silverware, the buyer sometimes deducts non-silver parts (weighted handles, hinges). Comparing several free quotes is the only reliable way to judge an offer: always relate the price proposed to the fine weight multiplied by the day's price. ## The process and the legal framework A buyback follows precise steps: identifying the item, checking the hallmark, weighing on a certified scale, calculating the fine weight, then applying the rate. The professional must present you with a clear, detailed offer before any agreement. The law frames the operation: above cash limits, payment is made by **bank transfer or cheque**. Proof of identity is required and the transaction is recorded in a register kept by the buyer. This formality protects the seller and ensures traceability. Before selling, check that your item is really solid silver: our guide on [the troy ounce and the gram](https://meilleur-rachat-argent.fr/en/guides/troy-ounce-to-gram/) helps you convert the price to estimate an order of magnitude. ## Frequently asked questions How can I calculate the value of my silver myself? Multiply the total weight by the fineness (for example 0.925 for 925 silver) to get the fine weight, then multiply that fine weight by the day's silver price. The actual buyback amount will be this result minus the professional's margin. Why do two professionals offer different prices? Because the silver price is the same for everyone, but each professional applies their own margin. The buyback rate, expressed as a percentage of the price, varies from one buyer to another, so comparing several quotes is essential. ## Read also [ Guide French silver hallmarks: Minerva, crab, complete guide ](https://meilleur-rachat-argent.fr/en/guides/french-silver-hallmarks/)[ Guide Gold-silver ratio: what it says about the right time to sell ](https://meilleur-rachat-argent.fr/en/guides/gold-silver-ratio/)[ Guide How to identify solid silver: hallmarks and tests ](https://meilleur-rachat-argent.fr/en/guides/how-to-identify-solid-silver/) ## Sell at the best price near you Compare the silver buyers in your city.
