# 1 kg silver bar: investor format and buyback

Published on **28/07/2026** · By **Sébastien Joumel**

In brief

The 1 kg silver bar is an investment format in **.999** silver, supplied with a certificate and serial number. Its buyback value is calculated on **1000 g × the day's price**, less the margin; large formats carry a lower premium than small ones.

## A format designed for investment

The 1 kg silver bar (or ingot) is a standardised **investment** product, refined to 999 thousandths (.999). It usually comes with a **certificate** and an engraved **serial number**, which attest its weight and purity and make later resale easier.

Unlike collectible coins, its appeal rests solely on its metal content: no numismatic premium, but a known and verifiable silver content. Keeping the original packaging, the certificate and the purchase invoice helps document provenance on the day of buyback and lets you compare [silver buyback](https://meilleur-rachat-argent.fr/en/silver-buyback/) offers calmly.

## How its buyback value is calculated

The calculation is direct: a .999 one-kilo bar contains about 999 g of fine silver. Its metal value corresponds to this **fine weight multiplied by the day's price**, the world price being the same for everyone and quoted per troy ounce (31.1035 g), converted into a per-gram figure.

The difference between buyers lies in the **margin** applied. One advantage of the kilo: large formats bear a **lower premium** than small bars or coins, because manufacturing costs are spread over more metal. To check an offer, relate the price proposed to the fine weight multiplied by the current price.

## Selling your bar in good conditions

At buyback, the dealer checks the weight, fineness, serial number and integrity of the bar. An intact bar, with its certificate, is handled more simply. There is no need to clean it: it is the metal content that makes the value, not the appearance.

Payment is made by bank transfer or cheque above the legal cash limits, on presentation of an ID and entry in the register. If your bar comes from an estate, keep the supporting documents: our guide on [selling inherited silver](https://meilleur-rachat-argent.fr/en/guides/sell-inherited-silver/) details the steps and the value of an original invoice.
