Selling your gold in Sceaux and in the south of the Hauts-de-Seine: the jewellers of the rue Houdan, or the refinery directly
In Sceaux, from the rue Houdan to the Robinson district, as in Bourg-la-Reine, Antony or Fontenay-aux-Roses, the jewellers and gold-buying counters are intermediaries: they collect the metal, often at a flat rate per carat, then resell it to a refiner, and the sale there is subject to the French flat-rate tax withheld at source. Less than three hours away via the A86 then the A1, Gold & Silver Company, in Dottignies (Mouscron), Belgium, is the refinery itself, open to private clients: a Belgian smelter-refinery of precious metals, approved by the Royal Mint of Belgium and holding the status of approved assayer, with laboratory, melting and refining under one roof. The buyback price is published every day, per gram and per carat, and it is net: nothing is added, nothing is deducted. From Sceaux, Bourg-la-Reine, Antony, Fontenay-aux-Roses, Châtenay-Malabry or Le Plessis-Robinson, the process is identical.
Coming to the refinery from Sceaux, or shipping
From Sceaux, allow less than three hours via the A86, the A1 then the A22 towards Tourcoing and Dottignies, with free parking on site and no appointment needed during opening hours; your items are weighed and analysed before your eyes and the offer is made to you immediately. Registered mail with declared value, after a call to +32 56 33 19 96, follows the same path: analysis in the laboratory, offer within 24 hours, return of your items if you decline.
How your gold is valued
The metal is analysed on site and valued at its real fineness, that is its exact fine gold content, at the day's rate, rather than at a flat rate. The appraisal is free, immediate and without any obligation to sell.
How you are paid
Payment is made by bank transfer, a traceable and secure means, within five working days of your agreement. Belgian law limits to 500 euros the amount that may be paid in cash when a professional buys precious metals.
What tax applies to a French resident who sells gold in Belgium
In France, the sale of precious metals is subject to the flat-rate tax on precious metals (TFMP), at 11.5% for investment gold, CRDS included, unless the seller opts for the actual capital-gains regime where it is more favourable. When the sale takes place in Belgium, the Belgian professional does not withhold this French tax and sends no tax declaration of your sale to the French administration. If in doubt about your situation, call us on +32 56 33 19 96.
To find out what your gold is worth, the simplest thing is to bring it to us: the office of our refinery, rue Arthur Roelandt 22 in Dottignies (Mouscron), is open on Mondays from 10am to 1pm, Tuesday to Thursday from 10am to 12pm and from 1:30pm to 5pm, and on Fridays and Saturdays from 10am to 1pm, without appointment; weighing and analysis before your eyes, immediate offer at the published price, and you remain free.
